NS,
use this as an exercise to follow the schematic and figure out whats goibg on with the board. It isgood practice and will make you a better and more informed builder. I didnt even use the ba2 output but instead used the F4 boards. Took some work, but helped me understand the circuit and board better.

Is your BA-3 a Complentary output stage or a SE output stage? The bias boards are different. The D or D+ would be the one the BA-3 output connects to. On the SE bias board (BA-1), D- is for the CCS gate signal. In the Comp bias board (BA-2) there should be no D-.
The store has some good schematics for the connection of the BA-1 & 2 bias boards to output boards but not BA-3?
It just replaces the original common front end of BA-1 & 2.

I am very lazy to check this out, but I didn't think there was connection with the bias board and BA3 (front end).
I thought the bias board only connects to the output stage eg BA2 or BA1 output.

The connections can be made in more than one physical location that is electrically the same.
In the BA-1 the D+ (Both of them) of the bias bd is connected to the output of the BAGS (D) and the gates of all the top FETs on one of the 2 D labeled points. I think there is 5 wire connect points labeled D or D+.

Thanks for all the reply's,
The ba-3 board is single out D is out G to gnd,
The bias board I think is made to operate with BA-1 It's balanced In and single out,so that's one single out for either board,am I correct so far,NOW here where I haven't got yet in building and smoke testing it,
The bias board,now ordinarily it was part of the front end then it changed to the output board single or complementary so 2 different circuits,
I after soon deep digging,D is D+ S is feedback from q102 on BASO V2.0 board,out to out D- to D-,I only have this output board so I can't say for the complementry board ,but It's bias is different,
The ba-1 is made for this output board,pad to pad,lol
I have ba-3 and ba-1 boards ,and I will build them soon It's the next build after Xoc1's TH,,,,,See any mistake or comments are welcomed!
Thanks for your help as always!
NS
