The thief broke into my house and .... no not really. Ok, so it was not mine at the time... I bought a Marshall AVT 150 head that "needs work" off Facebook Market place a few months back for a great price. Hey, I repair amps and things, this should be easy. I get the amp home start testing. Yup preamp works great, but nothing out of the main outputs. Ok, seems like a standard case of blowen TDA7293 on the output. I pull the amp apart and I see why... there are no output boards. Now I know why they wanted to make the transaction quickly.
