February 23, 20188 yr @Blueman2 Tks for clarification. Yes, I need 4 pair. Power supplies always come in handy
February 24, 20188 yr Hello, Please add me for a set of Dynalo Mini with TKd pot and PSU boards. I appreciate.
February 24, 20188 yr agree, yes, four sets power supplies, many projects to be completed. I changed the quantity to 2 sets Edited February 25, 20188 yr by samsie I double check my stock and realised that I have three sets at home already

Would anyone be interested in getting Grounded Grid or KGBH boards? I can provide gerbers. I'd like to get one or the other (or both) but if no one else is interested I'm not gonna rock the boat etc.
February 25, 20188 yr Author I can add them to the sheet. Are parts easy to be found for the KGBH? I always wanted to build that

I always wanted to build that Not the original one at least (2SA1968s for starters). I did see a thread for a BJT build of this, but didn't go thru it. One of the stat guys can advise you much better than I can though...
February 25, 20188 yr 4 hours ago, sbelyo said: I can add them to the sheet. Are parts easy to be found for the KGBH? I always wanted to build that There is a new version KGBH that uses current parts. I ran a GB on it last year. In addition to replacing the 2SA1968 as the CCS parts as Pars pointed out, this version also replaces the 2SK216/2SJ79 JFET with current production BJT parts.

I would be in for another set of these boards. The BH-BJT has become my favorite amp these days. Just love it. I would like to have another set of boards in case my son or brother decide they cannot live without one. Here are the gerbers. kgbhver6sbipolar.zip Edited February 26, 20188 yr by Blueman2

Does anyone know? Quick glance shows multiple heater connections Also curious if GRHV is the best PSU to use for this or if there is a different BH PSU that should be used? Gonna do some reading on the threads here tonight to try and find out.

I will add to the spreadsheet.

Gonna do some reading on the threads here tonight to try and find out. Yes, these work well with the BH. Good clean power with the ability to add timer function for the HV section. This allows the tubes to warm up for about a minute before the HV kicks in. The only real question is whether to use the on board Low Voltage which the GRHV provides, or whether you want to go with separate GRLV board(s). I used the GRHV on board LV supply and it works fine on my BH-BJT. Edited February 26, 20188 yr by Blueman2

February 26, 20188 yr seeing only a few people have signed up for Carbon boards. I have some version 6g from PCBNet 2mm/3oz, that I don't mind departing from (16.75USD/ea). If interested shoot me a PM.
February 26, 20188 yr Author EML 20B V4. Only $500 each. Good lord that’s enough to build another ampSent from my iPhone using Tapatalk seeing only a few people have signed up for Carbon boards.

February 27, 20188 yr Cheaper than WE300B reissued ! JAC Music got a pair for ~500usd, still pretty steep for a set of four.
February 27, 20188 yr Would the GRHV be appropriate for a 12ax7 + 6V6 play thingy or is it overkill or the wrong purpose altogether? I am playing around with some tube preamps but in a low voltage scenario at the moment since I don't have a high voltage power source currently. Edited February 27, 20188 yr by masamoto
February 28, 20188 yr Hi, Is the tube bal/unbal with power supply one stereo set? (I still want the reserved SS ones too) Steef
February 28, 20188 yr Author Hi, Is the tube bal/unbal with power supply one stereo set? (I still want the reserved SS ones too) SteefI’ve got your SS set put aside. I have to look at the Gerbers tonight to see if it’s one board per channel for the tubeSent from my iPhone using Tapatalk
February 28, 20188 yr it is one board per channel for the tube. your choice of tube front or tube back (different layouts)
