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.

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.

Superb looking cases ... can anyone do an English translation, such as prices for the cases, postage etc. ?

i know this is an old thread but i must say that you did a great job...

i checked out that link and it appears one of those cases will cost around $70Canadian shipped...

heh...anyone selling bpa300 pcb's yet?


Has anyone figured out how to order the cases?? I think this has a lot of potential. Looks better than Hammond and way cheaper.
