ah...for bridging two stereo amps, I guess

but starting from scratch, I thought 'X-balanced' would be better

well, maybe its better to go slow on the balanced subject...its still early days for this thread and it might go on for a long time

I'll pause for the time being and wait to explain its operation.

well, in any case, before going balanced for real, we need a working amp, at least

Two threads already explain [by analogy] the operation of Conjoined Twin AB100. They are "Conjoined Twin DiyF6s" and "Bridge a pair of F5s" in the Pass Labs Forum.
Best regards.
