[drakelist] OT: Difference in Vibroplex bugs
[EMAIL PROTECTED] made an utterance to the drakelist gang -- hi, I sent this to my CW mailing list but there's a much larger audience here so i'm sending it here as well... Just wondering if anyone could help me figure out the difference in some of the various Vibroplex bugs. I've found about 4 different variations: Lightning bug Original bug Blue Racer bug And then for the Lightning bug i've noticed some have a square looking damper for the arm, others just have a post for the arm to rest against. If I were going to find one of these to buy and USE are there any concerns using the really old bugs vs. using the new bugs? I've got a deluxe original made in 1986 that is quite nice but I thought i'd have a little fun with some of the really old ones... but I don't know if the old ones are more trouble than they are worth. Thanks for any advice and recommendations.

Vibroplex sells a product called a bug tamer which is essentially an extension to the arm, permitting the weight to be mounted farther out on the arm, slowing the speed. Slow speed on a blue racer is around 22 WPM, I think. Al's comments were right on - it's really about adjustment, not age. Thanks - sounds like they'd all be a nice fit then. My biggest concern was that the models with the triangular pivot mechanism (or the non-jeweled mechanism) would be prone to problems, etc. My original deluxe seems to be stuck at around 35wpm with the huge weight at the top of the arm.

Re: [drakelist] AC3 vs AC4 ?
[EMAIL PROTECTED] made an utterance to the drakelist gang -- On Wed, 4 Jan 2006, Ron Wagner wrote: One big difference is that the AC3 has a set of resistors in the bias line. Those resistors are jumper shorted out normally with a small screw. Lifting the jumper short allows you to easily measure the idle current (actually voltage across known resistance). Much easier then trying to look at the fat needle against fat marking. You can measure the current on the resistor under the chassis too, and should to make sure the finals are balanced. But to set the current easily the AC3 was a gem. IMHO. You touched on something that I noticed when I was trying to align the bias current on my AC-3 (and haven't tried yet with AC-4)... I wound up leaving the screw connected and measuring the voltage off of the connection to the filter C (will have to review the schematic to tell you which one). Can this same trick be used on the AC-4 or is this an AC-3 only operation? I had to pull the bottom cover off of the AC-3 to do this - I couldn't make heads or tails of the TP-1 reading with the jumper screw removed.

[drakelist] T-4 Reciter question - neutralization in general
[EMAIL PROTECTED] made an utterance to the drakelist gang -- hi, I got my early xmas presents yesterday, an R-4 and T-4 reciter (I think the T-4 serial is 106 or something low like that). The 6JB6 tubes were pretty soft - around 70 watts when gain cranked fully CW on 40 meters. The long story made short is I pulled the old 6JB6 tubes out and replaced them with what appear to be new sylvania. I don't think they're matched because the design of the plate is slightly different. They're both 6JB6 Sylvania but look a little different inside. I followed the procedure in the manual to neutralize them at 28.8mc with a nice bird dummy load. I got them neutralized fairly quickly with max output at the bottom of the dip on 10 meters. I don't remember exactly what the final power out was, but I think it was around 90 watts. Now the meat and potatoes of the question - on 40 meters the bottom of the dip is not max output - the bottom of the dip is about 5 to 10 watts less than max output. Did I make a mistake? I never run 10 meters so optimized operation on 10 meters isn't doing me any good. The 10 watts that I'm losing by running at the bottom of the dip on 40 meters doesn't bother me either - I just wonder if I missed a step or if this is typical behavior?

It's the weak ones that show up as S2 or S3 on the R-4B that don't move the needle at all on the R-4. Weird.

They ran 24/7, and often made transmissions in excess of 30 minutes, AT FULL POWER. In this service, the finals lasted a little over two years, typically, with end of life defined as 100W output on 20M. This piqued my curiosity again - Let's say you're running your T-4XB at full power for 30 minutes at a time at 300mA and the plate is perfectly dipped. All is good. But if the plate isn't dipped at 300mA and would be at 240mA if dipped properly there would be 60mA of current wasted as heat running at 300mA. But it's still 300mA, whether resonant and dipped at 300mA or splattering at 300mA - the thing i'm wondering is if the tubes are suffering more at 300mA undipped or if the life expectancy the same as 300mA dipped perfectly, being paced at a rate of current (heat) travelling through the metal. And I suppose the other question is what is a plate dip anyway - can I think of it as if the tank circuit is sucking the power out of the tube or is it best to think of the tank circuit as a valve that passes the power when at resonance, and the current increases as the RF power output is backed up and can't get out? Sorry for the rudimentary questions but I can't find this online anywhere and don't have an old ARRL handbook that explains it. thanks -- 73 Jason N1SU http://n1su.com/ -- Submissions:drakelist@www.zerobeat.net Unsubscribe:[EMAIL PROTECTED] - unsubscribe drakelist in body Hopelessly Lost:[EMAIL PROTECTED] - help in body of message Zerobeat Web Page: www.zerobeat.net - sponsored by www.tlchost.net --

At 50W load for a typical R-4 the voltage drop by the thermister probably isn't much, but 400W load for the AC-4 would probably reach the maximum permissible 10% voltage drop range adding to frequency drift during key down. 100VAC is too low methinks ;-) I experimented with one of them for feeding my AC-4/T-4XB and the panel lights dimmed enough to make me nervous with 80W PEP CW output. liberated one from a dead PC supply and installed it in my AC4, and there was a noticable reduction in the turn-on thump.

If you have any sitting around, let me know how much you want for them! Try to find some chimneys with the tapered tops to push air across the anode seal and plate heat dissipator. If you use glass cylinders that are not tapered at the top (Coleman lantern glass) you might as well not use any at all. This depends on your operating style, however. If you rarely run the tubes beyond dull gray with a tint of red you can get by without a proper chimney. If you run the tubes red to almost orange (pretty easy to do with 3-400Z) you will want chimneys with the tapered rim. The glass envelope can take more heat than the anode seal where the pin comes through the glass. As for the tubes, my recommendation would be to buy from someone who has used tubes in good working condition (sometimes Tom's Tubes has some nice ones that are used). I've blown a lot of money on crap sold at the auction sites - I have a shelf of dead 3-400Z and 3-500Z tubes that were sold as is - $300 worth of junk that would have bought a NEW matched pair of 3-500ZG. Late model 3-500Z Eimac tubes are prone to leaks and usually fail immediate on turn-on if they haven't been used for 10+ years. Last but not least, if you see about 2500V in SSB position and 160mA or more idle plate current you might want to consider good chimneys because the tubes will get awfully hot. My L4 will deliver 650W with 65W drive in the CW position with 3-400Z and it will run forever on any band - do this in SSB mode for another 2dB (1100W) without good chimneys and you'll melt the solder in the tube pins and ruin your tank coil or bandswitch on WARC (17m operation for example).
