    BA115 - DC on speaker output

    Hi - I've found multiple issues with this amp....replaced the zeners (D8 and D9) - one was shorted out - now the LED comes on versus no LED prior. I've also replaced Q2 and Q5. But I'm seeing -34v at the speaker and when I run a signal into the amp, I see it die around Q6 area.

    Any ideas would be helpful!

    Thanks!
