Two P-BASO-2V20 output boards and two P-BASB-2V20 bias boards. The bias boards are only available in this set. Populate this set with your components and the P-BAGS-1V20 gain stage, then add your own power supply, chassis and heat sinks to complete the BA-2 amplifier in the 3 output pair per channel configuration recommended by Nelson Pass.  If you want more output devices order another pair of output boards here.

It was time to build a BA-1 with SE Output

The BA-1 Monoblocks are finished. Beautiful sound - a bit special - perhaps the single ended class A concept.
I like this amp!

BURNING AMPLIFIER SINGLE-ENDED BIAS AND OUTPUT SET FOR THE BA-1 & BA-3

Quality product like all DIYAUDIO products. There is a zener diode mis-labeled as 2N4739, it should be 1N4739. It is a 1 watt 9.1 volt devise.
It was a challenge to find the correct schematic as the board part numbers were not the same as the linked one. This is the correct place to see it. https://www.diyaudio.com/forums/diyaudio-com-articles/154777-burning-amplifier-ba-1-a.html
Also, see attached schematic.

Quality Boards

One thing that I didn't realize is on my Macbook the BOM link auto downloads an Excel file without a notification. I missed the download at first.
Really like the high quality DIYAUDIO boards.

The boards are of excellent quality. Delivery in under 3 days from USA to Germany - supersonic!
Still collecting parts.

good quality boards but with a slight tracing defect

Hello,

The service has been great; communication as well and the product is almost flawless if not for a slight trace error on the drain of Q5 that is easily fixed adding solder (if not detected the circuit still works unaffected until a certain load).
So overall thank you for a good service.
