Riddle Me This!
Good Morning, I have just completed a 1250 rebuild with the help of parts list from MTF and Mattsd, thanks guys. Here is my problem: getting ready to power her up on the 100 watt DBT I have just the protection and stabilizer plugged into the unit. I get a dim bulb and 65VDC on both sides of the stabilizer. I then attach one of the power amps to the left side of the receiver, the bulb dims but not all the way and now i'm getting 40VDC on the stabilizer both test points. Same thing with the right side power amp board. Idle current is out of whack on both power amp boards. I rechecked all my transistor and cap positions on both amps and all look ok. I did have a slight problem with the equalizer when rebuilding that. Before I started redoing that board I noticed an entire trace was lifted and broken on the back of the board. I fashioned a jumper wire to connect the base of Q12 to R41 & R42, not sure if that is the problem but I'm stuck here now.
Schematic is attached of the equalizer.
Thanks for the help!
