Phonic P8A schematic
Just for reference, I managed to acquire the schematics for phonic P8A active monitors which I am currently rebuilding and tuning. They didn't send me the full service manual but chances are the other models (P5A, P6A..) use the same or similar amp.

Also from googling and inspecting the closeup images there is a reason to suspect that older Behringer monitors (B2030A and B2031A, not sure about B303X series) differ very little from these - they all use three TDA7293 chips and nearly identical eq section.

I will send the schematics to anyone interested if you pm me your email.

Yeap, I'm having a problem with one and trying to troubleshoot it. Would really appreciate the schemo too, if possible. Thank you!

I know it's been a while since you posted this, but I just picked up a set of the P5As and could really use a schematic. Even if it is not exactly the same, hopefully it will be close enough. Would it be possible to send me a copy? Much appreciated!
