I have got emails about the buying the PA150 PCB. I only have a few left. If there are enough interest I may be able to make some more.
Please reply here if you are interested in the PCB. If the total number is > 40 PCBs, the cost would be about $10 per PCB. Shipping would be extra.

I will be glad to donate some Vishay/Dale WSR 0.3R 2W 1% resistors to everybody (3x40 PCB I guess) who ordered a pcb. I would like to build a BPA style amp, and this is the most complete pcb I have seen before. Alex I would really like to help in getting this pcb available to DIY builders.
my only concern would be adding a additional pad/footprint for other size input caps for C1. just to provide options.
I am interested in 6-10 pcb's really just depends. I cannot commit to all 10 at this time.

Does a single PCB 50% or 100% of a mono amp? i.e. How many would I need to buy to build 6 amps?
If you dont mind saying, how much did you pay for those cases? They look phenomenal but I can't read/write Chinese to order them. Maybe you could help do a second group buy if they are reasonably priced.

the DRV should be simple enough.you can p2p on proto-perf board......... I have several pcb for the DRV from digi01 still, and have balanced out from my DCX crossover. maybe someone will try with the twisted pear txd pcb?
I have the resistors (0.3 2w 1%)for the pa150 amp, ill see if I cant scrounge up the required SMT caps/resistors, and trim pots.

These are going to be so great. Can anyone answer my other question about the PCB's being a half or whole mono amp?
alexcd, you need 2 PCBs for a mono amp. For a stereo amp you need 4 PCBs.
For the cases I can't help here, as I am not satisfy with the web site that I ordered from. (www.my3c.net)

I could make it like this :
But if possible I don't want to change anything because my original board is tested and measured to be good. I just don't want to make any silly mistake on a 40+ PCB order.
I don't think that change is important enough. Leads should bend enough to reach the existing holes in most cases anyhow. No?

Has anyone figured out how to order the cases?? I think this has a lot of potential. Looks better than Hammond and way cheaper.
Very nice and clean construction, Alex... But try to think about different input amp - DRV 134 have little bit " synthetic " sound...
Do you suggest taking the DRV134 circuit apart and using other opamps in place? The resistors would have to be 0.1% and may be difficult to match opamps, no?
