Jetlag, I have the same model as yours (HB5-3/OVP-A). From what I've gathered here, some came with the varistor and some doesn't. I went to Fry's Electronic today and pick up an aluminum chassis since you had made fun of my previous chassis. It was a prototype :-). Anyway, thanks so much for your help. I'll post some pics of my finished product soon. -- F-100 F-100's Profile: http://forums.slimdevices.com/member.php?userid=4328 View this thread: http://forums.slimdevices.com/showthread.php?t=18491 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Here are couple pics of my DIY power-one power supply. FYI, I flunked out of Circuit 101 in my college years and changed my major from EE to CS so I'm no expert with building power supply here. But thanks to Jetlag's posts, I was able to gather enough information to give it a shot. BTW, I'm using an old external SCSI hard drive case that I found in my junk box for my test case.

Thanks. As you can read from my earlier posts I was using the PowerOne and it was working quite nicely, I just had not been able to find a case that I liked.

Again, I'm not certified or even experienced, but: It seems to me that if someone were holding it with moist hands- that persons body would be quicker to ground than a path including the outer enclosure-->the screw post-->the PS frame--> ring terminal conntection and ground wire-->then finally back out the ground on the IEC and into your receptacle. I've seen people recommend sanding down the finish of the case where the ring terminal attaches for better conduction, so I'm thinking a bolt might not be the lowest impedance path available. As noted, the fuse isn't going to reduce the shock hazard- so proper grounding techniques are pretty much the only defense you've got. Unfortunately you can't take my word for it (I've been proven not so bright a few times here) and will have to do research on these things before you can legally/morally sell them for profit. I would humbly suggest starting here: http://sound.westhost.com/psu-wiring.htm : On the fuse issue, there are IEC inlets with an integral fuse inside. -- Skunk Skunk's Profile: http://forums.slimdevices.com/member.php?userid=2685 View this thread: http://forums.slimdevices.com/showthread.php?t=18491 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

The question is - can I do it. I have never, never even attempted anything of the sort, but I am intrigued - Is this really "moderately easy" for a complete novice or is it "moderatetly easy" for someone with skills - I am being honest - I am probably the biggest novice there is.

OK, a couple of quick pics before I have to get some other stuff done. Desoldered the existing wire harness, cleaned up the contacts and soldered jumpers from 1-2, and 3-4. Then, temporarily clamped the mains onto 1 and 4, and got a very steady 5.06 VDC.

The best thing to do would be to put a 250ma slo-blo fuse on the mains side. The SB3 will draw around 1 amp so you should put in a 2 amp fuse if you are going to fuse the DC side. No need to do both - personally I would go with the mains fuse. Also keep the 5v output lead as short as possible otherwise you will need to use the load sensing facility but as squeezeme points out it may be a challenge to get four wires into that plug!

I will do some soldering and let you know how the voltages change. Gotta run to Radio Shack to get some stuff. One last question, don't both the SB2 and SB3 draw a bit more than .5A?

I think you mean the CDA266? Anyway, it's getting a lot closer with the XDacV3 and upgarded PSU, but you can add a tube stage and power supply to the XDac to improve it further. Once you do that though, you're getting close to the price of a NuVista Dac, which is supposed to be excellent.

I haven't said a lot about it here because I wanted to live with it for a decent amount of time before making a judgement and I get a bit tired of people raving about their systems (the disappointed rarely post!) but i can certainly say its the best sound I've ever had and opens out the sound significantly.

[SlimDevices: Audiophiles] Re: Best mod?
Pure output current is not the whole story. The power supply should offer a low source impedance at the frequency of operation - there's no point being able to supply lots of amps at DC if the source impedance increases rapidly with frequency. You only have to look at the schematic of an Audio Research or Naim amplifier to find that as much goes into the power supply as the amplifier itself. In effect, you use a wideband amplifier to supply DC to the load. With more basic power supplies, you can go some of the way by simply decoupling the supply line to ground with one or more electrolytics, bypassed with one or more polypropylene and ceramic capacitors which behave better than electrolytics at higher frequencies. The electronics effectively sees the decoupling capacitors as a low impedance shunt to ground from the power lines. For an SB3, a DC current of 3A is plenty and I daresay it already has the decoupling I mentioned. My approach to replacing the switched-mode power supply with a linear one would be (haven't done it yet) to provide a wideband regulator, remote sense (so that the voltage being controlled is the one reaching the SB3 power connector allowing a longer cable and not being concerned with voltage drop), and possibly a capacitor upgrade in the SB3 itself. Not especially keen to void the warranty, so may just make do with the first two. However, to my ears, there's not a lot wrong with the SB3 as it stands. -- DitherMan DitherMan's Profile: http://forums.slimdevices.com/member.php?userid=3189 View this thread: http://forums.slimdevices.com/showthread.php?t=18491 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

I posted this over on the Audiocircles forum yesterday but thought it might also be of interest to this group. I hope its not violating any rules to repeat it here. Over the holidays my brother-in-law and I bought several squeezebox 3s and went about modifying them in a some what systematic fashion. We would make changes to a unit and when that sounded better than the stock unit then that become the reference and we evaluated future changes against the best sounding one. The version that we settled on as sounding best was as follows: 1)Power supply upgrade - just replace the stock wall wart with a surplus regulated 5v supply. The one we used was surplus from some SGI equipment and was rated at 1A. Opening it up showed it to have a hefty transformer and a nicely regulated output. 2)Digital output upgrade. We replaced the stock output RCA with a 75 ohm BNC connector. The one we used was made by Amp and sourced from Digikey - their part number A24598-ND. We also changed the wiring to the output jack. If you trace the wiring, you see that there are 2 inductors in the output path, L8 and L9. We removed these and took the digital output directly from the resistor voltage divider further upstream. I don't have the unit in front of me but I believe the resistor numbers are R55 and R56 - 107 ohms and 245ohms. We also added a transformer output using Scientific Conversions SC916-01 1:1 shielded digital transformers. 3)DAC upgrade - We changed the stock PCM1748 to a PCM1748KE and found the higher grade DAC chip to be a significant improvement. 4)Analog ouput - We removed the output op amp entirely and removed associated output caps from this op amp and from the PCM1748. The signal was taken directly from the PCM1748KE chip. Blackgate 4.7uf N 50v capacitors were used for the output. These were mounted directly at the RCA output jacks and then wires were run back to the DAC output. It was important to remove the unused op amp. I'm not sure if the reduced power draw of the op amp helped the DAC power or if the op amp was picking up noise and amplifying it but things sounded cleaner with the op amp gone. Another change we evaluated but did not like was replacing the power supply caps on the DAC chip with Black Gate 47uf 16v Std caps. We found the sound degraded compared to the stock surface mount caps and switched them back in. When we started we found the best sound came from the Toslink output going to a Monarchy DIP dejitter box to a highly tweaked ART DIO. Preamp was a Manley tube preamp and the power amps were either homebrew 211 amps, homebrew UCD400 amps, or Nuforce Ref 8s. The SPDIF out was the next best sound and the analog output was a distant 3rd. At the finish the best sound came from the analog outputs with the SPDIF a small but noticeable distance behind followed by the TOSLINK even further back. ---Gary -- GaryB GaryB's Profile: http://forums.slimdevices.com/member.php?userid=3169 View this thread: http://forums.slimdevices.com/showthread.php?t=18491 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Just put my SB3 on a linear power supply here in Switzerland. It's a 2.0Amp <2ppm supply and subjectively listening (too lazy to compare objectively to the original supply, had it going for 2-3 weeks though) to it, I would say, it's a clear improvement albeit not breath-taking. The top is more detailed (but became a tad bright as well) and sound stage is definitely better (larger & more air around sound sources). Very musical now. One trick: keep the 5V cable part short, I have my @ 50cm and measuring the source I saw that 1m puts significantly more load on the power supply already. cross-posted with the 'replace the wart' thread here. -- prz prz's Profile: http://forums.slimdevices.com/member.php?userid=2826 View this thread: http://forums.slimdevices.com/showthread.php?t=18491 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

[SlimDevices: Audiophiles] Re: Best mod?
The power supply that the URL above points to is an unpackeged kit. It would appear to need a transformer and an enclosure as well. My suggestion would be to use something like an Acopian 5EB100 power supply, if this is the way that you really want to go. Here is the link to the Acopian page that describes them http://www.acopian.com/single-l-screw-1to9vt.html This unit is a plastic box with screw terminals. You would need to cut off the cord from the existing "wall wart", connect the wires WITH THE CORRECT POLARITY on the output terminals, buy a power cord and connect it to the input terminals. Be careful, if you reverse the output wires, bad things can happen. Also, you can have exposed 120 volts on the input terminals. This is probably not a modifiation for the faint of heart.

[SlimDevices: Audiophiles] Re: Best mod?
I found a window of opportunity to run a test using the SB3 phono outputs. I know what I like so do not expect any flowery hi-fi comments! For comparison purposes I used SB3 wall wart vs my PSU on digital out and phono out. Then I compared the internal DAC's to my external one. Phono cables were some Chord Silver Siren's. External DAC was Audio Synthesis DAX Discrete connected by Chord digital cable. First up was the SB3 supply with phono connection. Bit of a shock having spent the last week listening to my current setup as the sound was thin with lack of low end and a jarring sharp overall sound. Sounded like a budget CD player. OK if I was in the next room but not for me if I was sitting in front of the speakers. Next I connected my PSU (for which I claim no design credit - off the shelf RS item that had the right provenance) and there was indeed an immediate improvement. Bass was back, separation was excellent, good frequency range with no 'nails on glass' sound and I actually found myself listening to the music and forgetting why I was there. Remarkable change. Finally I went with the new PSU and digital outs to the DAX. The sound was better than the phonos but not $8,000 worth. For serious listening (and bear in mind it is a legacy device used for CD) I doubt it could be bettered and is the one I will stay with. Almost as good as my Theta CD player (but way off vinyl, but that's another story!). Tried the SB3 supply just to remind myself and the sound dropped to somewhere around the 'phono with my PSU' mark. So in summary this particular PSU probably makes more of a difference if you are using the internal DAC's. They are obviously well designed and stand comparison to an external DAC. If you want to improve your SB3 this is a worthwhile upgrade and more cost effective than buying an external DAC. Please bear in mind the same results may not apply to other makes of PSU, just this Lambda unit.

"I judge a product by the initial results" You should also consider the initial cost. When you look at what this product does for you it is a rare bargain. Wifey loved it right out of the box. She used to ask me to put on music but now she helps herself. Even suggested getting another SB. The stock PS is just fine for equipment in this price range. High quality power supplies are quite expensive. The expense is only justified if you want to push performance and have equipment that allows you to realize the gain. I bought a cheapo surplus linear supply and noticed improvement in exactly the areas you mentioned "Undefined low end, way to laid back middle and unfocused top." Basically, lacked any refinement in an audiophile sense. It's not like oh, now I'm completely satisfied, but it shows enough potential with the surplus PS that I've ordered a Red Wine modded SB3 and if that works out will be looking for a well designed PS to replace the surplus linear. You may never be satisfied with the sound for critical listening, I don't know, but just the convenience makes this product a worthwhile purchase for anyone that has a stereo and a network.

I am eagerly awaiting your judgement on the possible (hopefully) improvement in sonical character of internal dac when used in conjunction with your recomended psu kit. The sound from the stock sb(internal dac)/ps combination was a dissapointment. Undefined low end, way to laid back middle and unfocused top. The best way to describe my feeling after 20 hours of hopefull playing-in time, is that the initial feeling of "washed out" sound will just not clear up. I stand puzzled why such a revolutionizing product with such potential could possibly be in a lose all or win all situation by such a shortcoming. Why must the enduser take the risk in having to obtaine a comparably costly ps to possibly get the best from the squeezebox, controlled and open sound that obviosly lies hidden in the designs potential with just a solid power supply. I just doesnt make sence to me even if it´s big volume discount,universal compatability,environmental and profit margins, using a sub par switching power supply with HF noise. I judge a product by the initial results and not by what can possibly (hopefully) be achived with a simple tweak. It´s really confusing for the end user not getting the full potential directly. I hope i dont come across cynical its just that i am in a situation of do i return it or invest in a linear power supply with the right kind of juice.

Testing starts this evening. http://i5.photobucket.com/albums/y186/q-max/DSCF0124.jpg http://i5.photobucket.com/albums/y186/q-max/DSCF0125.jpg -- Heuer Heuer's Profile: http://forums.slimdevices.com/member.php?userid=2543 View this thread: http://forums.slimdevices.com/showthread.php?t=18491 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

I tried this, and while there wasn't much in it, I think using an optical lead wired sounded slightly better than wireless. Slightly being on the limits of perceptibility. Tried the same experiment with coax (actually UTP) and either my ears had faded, or there was no difference. I was using a linear psu for all this - have yet to discover if this makes a difference or not! -- bludragon bludragon's Profile: http://forums.slimdevices.com/member.php?userid=1530 View this thread: http://forums.slimdevices.com/showthread.php?t=18491 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

You really need to get +/- 0.1V. There is something wrong your power supply if it's off by 10%. Under/over-voltage shouldn't hurt SB2/3, but it may function erratically. I can tell you for sure that the display and analog stage will not function correctly below 4.6V, and below 4.9 is questionable. If you're going to use an aftermarket supply try to get it dead-on 5.0. Linear supplies are usually easy to calibrate - measure at SB3, not the output. A shorter, heavier cable may help too. -- seanadams seanadams's Profile: http://forums.slimdevices.com/member.php?userid=3 View this thread: http://forums.slimdevices.com/showthread.php?t=18491 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Well, I hope you can test the digital output. I'm very interested to hear (pun intended) the outcome. -- ezkcdude ezkcdude's Profile: http://forums.slimdevices.com/member.php?userid=2545 View this thread: http://forums.slimdevices.com/showthread.php?t=18491 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Rest of my PSU parts arrive tomorrow so I should have a working linear supply by Thursday. I will then do a comparison but in the interest of fairness I will use my resident 'Golden Ears' - my wife. No interest in technology but she does have the ears of a bat. I can put her in front of a system, tweak it and get an instant answer which tends to be in the categories of "better", "worse", "can I go now"! -- Heuer Heuer's Profile: http://forums.slimdevices.com/member.php?userid=2543 View this thread: http://forums.slimdevices.com/showthread.php?t=18491 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

I'm still not sure the board has reached a consensus. Does anyone think the linear power supply makes a difference for the digital output? -- ezkcdude ezkcdude's Profile: http://forums.slimdevices.com/member.php?userid=2545 View this thread: http://forums.slimdevices.com/showthread.php?t=18491 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
