Hi, I have a Onkyo amp A-8057 that I am troubleshooting and there is something I am not getting, see attached screen shot of the schematic. On the collector of Q513 I should get 1.43V and on the collector of Q515 I should get -1.35V according to the test points noted on the schematic. I am getting approx 50V and -50V since both transistor are conducting that makes sense to me. I have the same problem on both channels, orginally the power transistors were shorted, I replaced them and now the amp does not come out of protection mode. I don't not get why I should get 1.43.and -1.35V. It's been a while since I have worked with transistor I am probably a bit rusty. Note the schematic is for the A-8067, it is a very similar circuit to the A-8057 but this schematic has more test point on the schematic for debugging.
