Burning Amplifier Gain Stage Board (BAGS) which handles voltage gain for two channels when you populate it with your components. This board is required for both the single-ended BA-1 amp and the complementary BA-2 amp. 

BAGS is the Burning Amplifier Gain Stage board. Being the Front-End, this is where all the signal voltage gain of a Burning Amp comes from. It's main purpose is to provide adequate gain to drive the suceeding output stage of a Burning Amp assembly.

For use as a Burning Amp, it requires bias boards and output stage.  However it can also be used standalone as a pre-amplifier.

Please visit the Burning Amplifier Helpdesk Thread for any questions you might have and for a definitive list of links to all articles and discussions about the Burning Amps.

It was time for a BA-1

Fantastic pcb! Top quality! Very fast delivery around the world (USA-Germany) in under
one week.
I found a pair of TOSHIBA 2SJ109 and I thought I should build a BA-1 poweramp with the
singleended follower. Not finished yet. Intake board is done.

It was time to build a BA-1

I found a pair of original TOSHIBA 2SJ109 BL - I was searching for a long time.
Now it was time to start this build.
The BA-1 - pcb is of excellent quality. Delivery was extremely fast as well customs.
The fun starts now....
Can´t tell anything about the sound - not finished ;-)

Makes an outstanding linestage

Finally got around to giving the BA1 a try as linestage. Couldn't be more pleased. Very similar to the ACP+, but with dual rails. Offset was so stable that I removed the output cap with great results. A beautiful, single-ended gain stage!
