sbelyo Posted February 2, 2018 Author Report Share Posted February 2, 2018 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 Quote Link to comment Share on other sites More sharing options...
MASantos Posted February 4, 2018 Report Share Posted February 4, 2018 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? Quote Link to comment Share on other sites More sharing options...
Pars Posted February 4, 2018 Report Share Posted February 4, 2018 For the CFP you need one board per channel, so 2 for a stereo SE, 4 for balanced. Quote Link to comment Share on other sites More sharing options...
hfhimeka Posted February 5, 2018 Report Share Posted February 5, 2018 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. Quote Link to comment Share on other sites More sharing options...

I added the TKD 4CP2500 to the sheet as well Edited February 8, 2018 by sbelyo Quote Link to comment Share on other sites More sharing options...
Tinkerer Posted February 10, 2018 Report Share Posted February 10, 2018 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. Quote Link to comment Share on other sites More sharing options...
sbelyo Posted February 12, 2018 Author Report Share Posted February 12, 2018 Sorry Tinkerer... I added it now, as well as the THAT340 adapter PCBs. 1 Quote Link to comment Share on other sites More sharing options...
MLA Posted February 12, 2018 Report Share Posted February 12, 2018 Another board suggestion: the PSU board for the tube based ubal/bal board? Quote Link to comment Share on other sites More sharing options...
sbelyo Posted February 15, 2018 Author Report Share Posted February 15, 2018 Agreed... I'll change the title to include the PSU with the set Quote Link to comment Share on other sites More sharing options...
sbelyo Posted February 15, 2018 Author Report Share Posted February 15, 2018 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?

DronEvil Posted February 19, 2018 Report Share Posted February 19, 2018 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. Quote Link to comment Share on other sites More sharing options...
mwl168 Posted February 22, 2018 Report Share Posted February 22, 2018 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?

sbelyo Posted February 22, 2018 Author Report Share Posted February 22, 2018 (edited) 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, 2018 by sbelyo 1 Quote Link to comment Share on other sites More sharing options...
mwl168 Posted February 22, 2018 Report Share Posted February 22, 2018 Wonder if anyone is interested in the solid state ubal/bal and diamond buffer boards? Quote Link to comment Share on other sites More sharing options...
sbelyo Posted February 22, 2018 Author Report Share Posted February 22, 2018 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 Quote Link to comment Share on other sites More sharing options...
Pars Posted February 22, 2018 Report Share Posted February 22, 2018 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. 1 Quote Link to comment Share on other sites More sharing options...
sbelyo Posted February 22, 2018 Author Report Share Posted February 22, 2018 That makes sense. I moved it down to 2, does everyone want to go to 1? Quote Link to comment Share on other sites More sharing options...
cspirou Posted February 22, 2018 Report Share Posted February 22, 2018 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. Quote Link to comment Share on other sites More sharing options...

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?

Blueman2 Posted February 23, 2018 Report Share Posted February 23, 2018 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. Quote Link to comment Share on other sites More sharing options...
