January 31, 20188 yr Some Gerbers... Schottky diode bridge board, vertical diode mtng: Potentiometer: TKD 4CP601 Only TKD 4CP601 / 4CP2500 TKD 4CP601 / 4CP2500 / Alps RK27 Quad GRLV 35mm SiC diodes https://www.head-case.org/forums/applications/core/interface/file/attachment.php?id=21170 Latest CFP2 https://www.head-case.org/forums/applications/core/interface/file/attachment.php?id=20304 Note for those wanting to do one of those balanced: you might want a uBal board to front end that. Bridge_Vert.zip TKD 4CP601 only final.zip TKD 4CP 2 pot final.zip TKD 4CP 3 pot final.zip EDIT: If you have either of the CP2500 boards run, make sure they thru-plate the slots.

February 2, 20188 yr Author Many many thanks... I'm thinking the 2 pot board would be fine unless you all want the alps support. I shall clean up the initial post and add the boards we're considering in there
February 4, 20188 yr I want to add cfa2 boards to my order. Are these for the single ended version? Do I need one or 2 boards for a 2 channel amp?
February 4, 20188 yr For the CFP you need one board per channel, so 2 for a stereo SE, 4 for balanced.
February 5, 20188 yr When do you expect to pull the trigger on this GB? I'm trying to figure out how much time I have to research the # of boards I might need.

I added the TKD 4CP2500 to the sheet as well Edited February 8, 20188 yr by sbelyo
February 10, 20188 yr The HV900 revised boards still aren't up on the sheet yet. I know I might be the only guy that wants them, but I will pay the price for a set even if it's kinda high. I need it to finish my build, and it would sure be nice to get them with the couple other things I want in this GB.
February 15, 20188 yr Author As far as the THAT340 adapter PCB's go, I'm checking to see if the board house can deal with boards that small. If not, I was thinking that we could do one board with several adapters on it then have a V score that would separate them. What do you all think?
February 19, 20188 yr I'm interested in some GRLV and HV boards. Is it cool If I just add myself to that spreadsheet? This is my first GB on here so I just want to make sure i'm follow proper etiquette.
February 22, 20188 yr Just added my orders to the spreadsheet. I have one request; for the unbal/bal tube board, since we'll be mounting the tube sockets on it, should we consider ordering the boards in 2mm thickness?
February 22, 20188 yr Author I'd agree with that, adjusted. The Dynalo Mini also adjusted to 2oz. Thanks to whoever cleaned up the columns. The board house can work with the THAT340 adapters so those are a go. I'll move the links to the board files onto the 1st post so everyone can see what is being ordered. Also, I feel like I forgot one board that someone wanted. Does the list look complete? Edited February 22, 20188 yr by sbelyo
February 22, 20188 yr Wonder if anyone is interested in the solid state ubal/bal and diamond buffer boards?
February 22, 20188 yr Author good question... I have one set left over from the last one that's reserved for steef. I think I may have one or two extra as well. If anyone wants a set let me know
February 22, 20188 yr After working with the mini boards in 3oz copper, I would strongly suggest going 1oz... Little parts and the heat to do heavy copper isn't a good combo. But I won't be buying any, so go with what the majority wants.
February 22, 20188 yr The tube ubal/bal boards are 2 x amp boards + 1 x power supply board? Also KG had two versions, the tube mounted on the same side as the components and megatron-style where you can mount the PCB on the top plate so the tubes can stick out the top. If there's a vote I prefer megatron-style.

If there's a vote I prefer megatron-style. I believe that's the config but I will confirm with Kevin. For same side vs megtron I vote same side... Feel free to cast your vote and we'll go with the majority. Can we setup a poll in this thread? Or is that not possible? Edited February 22, 20188 yr by sbelyo
February 23, 20188 yr Note to people signing up for the GRHV boards, this is the pair of boards (Left/Right or -/+). The pair are what you typically need for one high voltage amp. DronEvil, samsie and bluebyte60, you signed up for 4, which means enough for 4 HV power supplies. Just wanted to make sure you wanted that many.
