Re: [SlimDevices: Audiophiles] Welborne Power Supply for SB3
Intresting tread ? post your findings if the power supply actually works? and also if it doesn't ;-) I'm one off the por sods thats ordered one off these powersupplys but didn't get anything (ordered in april)nobody answers my email. So i'm asuming Welborne is f***ing me beware! do not order anything from them. Go and search AA and other fora for accounts off wellbornes buissness methods If i actually get my supply( i don't think so) i will be very carefull before conecting it to my SB. It seems like a god idea' to measure the output vs inputs and chassis etc on your SB and Hifi. -- Mnyb Mnyb's Profile: http://forums.slimdevices.com/member.php?userid=4143 View this thread: http://forums.slimdevices.com/showthread.php?t=39714 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Welborne Power Supply for SB3
I have two supplies. The first one was the one I had problems with and have since fixed. It works great, now! After building that one and LEARNING from the experience, the 2nd went together in NO TIME... heck, I'll put yours together for less than the $100 Welborne wants to do it! ;-) By the way, I did confirm output voltage before plugging the first supply into my White SB3. It powered up fine, but the SB3 was HUMMING, as I know now, because of the transformer leg shorting to the case. It fried my Black SB3 because the metal case was touching the metal legs of the SB. I'm letting them both 'cook' for a while. G'luck with your order!! It's all fixable and NOT worth getting worked up over. It's not like I lost my house in the fires or anything... this is just STUFF!!

Re: [SlimDevices: Audiophiles] Welborne Power Supply for SB3
i have one of the pre-assembled power supplies from welborne labs (i haven't yet learned to solder that's my next project!). no their stuff isn't 'junk' they have consistently gotten great reviews over the years. the problem seems to be their owner isn't really capable of running his business correctly. i was one of many who had placed an order and then shortly after the web site informed us that they were moving and all orders were on hold. rumors on many boards also stated that the owner was having some sort of personal problems but that's not for me to say. many people suffered through loooggg delays and most asked for refunds (which there also seemed to be problems recieving). their was no phone numbers or email addresses given to customers waiting for their paid for merchandise. some filed complaints with the BBB. i recieved my power supply for my SB after approx. 3 month wait. it came in the wrong color, i ordered red and got a black one. but after reading so many horror stories i figured it was better to live with black. it IS an excellent unit. i know when ordering kits their have been complaints of parts missing. i would love to order from them in the future as i really want some of their products, but i would be hesitant to do so without some prior reassurances from their owner. although these problems stem from this whole 'moving' issue, there seems to be long standing problems with his customers per other audio message bb's. -- ratso ratso's Profile: http://forums.slimdevices.com/member.php?userid=11493 View this thread: http://forums.slimdevices.com/showthread.php?t=39714 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Welborne Power Supply for SB3
OK, so I found the problem with PS #1. I opened the box and discovered the leads from the regulator and one of the leads from the transformer were touching the center channel (support beam, of sorts) of the box!! Taking the card out and putting friction tape across the entire bottom of the card, as well as trimming back the leads, solved the HUM problem. HOW I was still getting 5VDC out of it I'll never know!! Also, looking back at what happened when my Black SB3 blew, I think the case of the PS was touching metal of the rack the SB3 was sitting in. The SB3's metal legs were also touching, so KA-POW!! (especially with the above mentioned contact from the transformer and regulator) Anyway, the finished PS is great, clean and working. I'll start on the 2nd one with the same precautions for the bottom of the board. The blown SB3 is being sent back to Logitech for repair at a cost of $90. My fault!! I let both Ron Welborne and Wayne Waananen from Bolder Cable (who had been helping off-line) know what I found. If anyone is considering building this kit, it IS a tight fit inside. Make sure you follow ALL directions and keep the leads under the board trimmed back and isolated with friction/electrical tape as necessary. -- Eric Seaberg Eric Seaberg - San Diego [EMAIL PROTECTED] Eric Seaberg's Profile: http://forums.slimdevices.com/member.php?userid=7896 View this thread: http://forums.slimdevices.com/showthread.php?t=39714 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Welborne Power Supply for SB3
If its from Welborne it is JUNK. I have one. Its in the storage room. Don't waste anymore time on it. And yes you are lucky you got anything at all from Welborne. He sent you a kit that was missing parts! No surprise. I bought a preamp kit. I spent over 2 months and over 30 emails and never received all the parts. If you charge the item to a credit card, send the items back and have the credit card people get your money back. They will do it. -- donwalker donwalker's Profile: http://forums.slimdevices.com/member.php?userid=10816 View this thread: http://forums.slimdevices.com/showthread.php?t=39714 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

I did not make negative comments concerning the efficacy of wellborne gear. Therefore it is not germane whether or not I have listened to his products. I simply alerted the OP to the many posts about wellborne on other fora concerning the fact that wellborne takes the money and in many cases never sends the product and doesn't give refunds, according to the many complaints on these fora. It appears Wellbone owes a lot of people momey and gear . Perhaps you should read posts more carefully and make sure you understand them before you respond to them. Your response to mine clearly indicates you didn't understand it and it seems your are the victim of your own sloppy thinking. -- tomjtx tomjtx's Profile: http://forums.slimdevices.com/member.php?userid=7449 View this thread: http://forums.slimdevices.com/showthread.php?t=39714 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
[SlimDevices: Audiophiles] Welborne Power Supply for SB3
I bought two of these for my SB3s. Neither one came with the printed circuit boards, so they had to ship those. I put the first one together last night and discovered the power cord is too big to fit through the supplied strain relief, so I went to my neighborhood hardware store today and bought two that would fit. I just got the first one together, verified it was supplying 5.13V and plugged it into my SB3 in the master bedroom. This player feeds Genelec powered monitors (model 8020). As soon as I plugged in the supply the Genelecs started 'humming', most likely due to the fact that they are grounded and the Welborne supply isn't. It's odd that Welborne supplied a grounded AC cord but doesn't connect the chassis ground to anything. Is there any way to fix this? Has anyone else had a problem with these supplies?! For the price of $185 each, I am NOT impressed with what they sell! Since I haven't built the second one yet, I'm asking for a full refund including the two power cords I had to buy today! -- Eric Seaberg Eric Seaberg - San Diego [EMAIL PROTECTED] Eric Seaberg's Profile: http://forums.slimdevices.com/member.php?userid=7896 View this thread: http://forums.slimdevices.com/showthread.php?t=39715 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Welborne Power Supply for SB3
I haven't built this but I looked at what is published on Welborne's site. It looks like the entire psu including transformer is mounted on the circuit board which is isolated from the aluminum enclosure. Do you have the safety earth pin of the IEC connector referenced to the aluminum chassis? This is for your safety. The middle prong of the 3-prong IEC connector should have a short wire soldered to it, and the other end of the wire should be referenced to the chassis. You can use a captive O-ring for this and a good sized bolt with locking washers and nuts. Best to use brass which is easy to source. Desipite Welborne's recent customer service troubles, the gear is high quality. -- RioTubes RioTubes's Profile: http://forums.slimdevices.com/member.php?userid=10172 View this thread: http://forums.slimdevices.com/showthread.php?t=39715 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Welborne Power Supply for SB3
Welborn does ship a grounded AC plug/cable but doesn't use the ground. They actually state in the directions to trim it back to the strain relief and use only the HOT and NEUTRAL wires. I'll attempt connecting the chassis to the gnd of the +5 output to see if that helps. -- Eric Seaberg Eric Seaberg - San Diego [EMAIL PROTECTED] Eric Seaberg's Profile: http://forums.slimdevices.com/member.php?userid=7896 View this thread: http://forums.slimdevices.com/showthread.php?t=39715 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
