Hi, Marlowson
I am interested in the possible PCB deals on the BPA150 (originally by alex88). Does this board use smd or thru hole components? Also, what would be the estimated price per PCB? I am thinking of using a transformer to separate the + and - signals instead of the DR134 (I think) in order to bridge the two boards. Thanks!

In the field of components - no changes. Both smd and thru hole as in former alex88's project.
Price 8 euro apiece if you're buying 4 pieces.
9 euro if buying 2 pieces.
+ delivery man 🙂

Marlowson,
Thanks for the info! Hmm, I recall that there were quite a few smd components on the board. I am not that proficient with soldering smd - my right eye sight is not great. Anyway, a little off-topic, is there a BOM for the BPA150 archived somewhere. I would like to check to see how many smd's that I have to tackle with.
Thanks!
Reagards,
Go to the shine7.com website where alexw88 has almost all of the original information available for the bpa300 build. He originally set out to clone the Jeff Rowland amp and did a fabulous job.

I finish mine a few months ago, i disarmed it to work in the case and when i put back today i had a short circuit on the psu. the LED light start smocking and then blew up as i was shooting it down.
An externally hosted image should be here but it was not working when we last tested it.
psu,
I replaced the capacitors from 4x10000uF to 4x22000 last week and i retoched some joints in the area, i may have mess up, i hope the flash did notruin one of the capacitors.

Great recovery yakusa !
Looking forward to your impressions after a little burn-in. Your success prompts me to get my set back together soon. I stole the power supplies for another project but they can come back now. I'm using a Jantzen CrossCap now but want to see what the new Audyn Plus series will do.
I'll post and we can compare notes. 😉

Thank you for your help setting up the bias. Now I will start working on a Aikido 12VAC Line stage to go with it.
I'd rather use the boards from a forum seller, they looked of better quality. But you can always resort to ebay as a las option, just a tip.
