Sorry I meant with Q13 removed place the probes on the print of the pcb where the legs would go if it was still installed.
Regarding your update voltages it seems to be a drop of 40v going somewhere. If Q13 was removed and you remeasured these points it would prove Q13 was doing this. |

I pulled the collector on Q13 and powered on. The voltage reading jumped from 30 to about 70. So, thinking Q13 must be bad then? I have one on order..so thinking maybe I shouldn't try anything until I replace. What do you think? |
