well, so i understand no more gain is needed, a simple pot is enough, like other lm3886 designs. About the chassis, i think the distance between the toroidal and pcbs is greater in my layout design than the original shine7 design. I think it's worth to try an integrated amplifier design.

I have not ordered the boards for the second round yet 😉 Not even started requesting payment! I just managed to fit you in with some spare boards from last round.

Anyway back on topic, Who would be intrested in a full set of parts to go with your BPA300 boards? The price will be the same if not cheaper then ordering direct!

Please. Would be easier to get all the bits in one bag. 🙂

Will there be options like 'standard' and 'premium' on the parts?

Well, the part count for the BPA300 is pretty low. I will probably just use a standard 'premium' BOM for the kit. There only premium parts you can really use are;

C9 - C14
C1
C4

When i say premium, i just mean nichicon muse ES electro caps and a reasonably priced C1 film cap.

The parts will be somewhat premium, but the price wont.

Quite a few people have PM'd me asking me about my BPA300 build.

Well, here goes.

Traffo's: 2 X Avel lindberg 500VA 25V
Capacitors: 2 X 68,000uf 50v per monoblock
Enclosure: 2 X hifi2000 3u 300mm enclosures with heatsinks. 10mm panel (www.modushop.biz)
Balanced Inputs with no inbuilt line driver

Then the standard build on the boards.

😉
