Well, just looking at the voltages at Q604 (the transistor with the heat sink),?
Pin #17 (which should be the Collector voltage of +25vac) I¡¯m reading +60vac. ?When I put the positive probe on the C leg and the negative probe on the chassis I read 0 vac.?
On the Base and Emittor, I¡¯m reading 0 vac.?

Ned,
did you check the power supply voltages ??
Funnily, the other day I was able to download?
the T-500 Service manual from?.
Unfotunately I forgot to download part II, which contains most of the circuit diagrams. I kusted wanted to lookup the points where to measure the 15 and 35V.
unfortunately. I just wanted ... ?15 and 25V
When I try to dowload it now I¡®m getting
?Item not available due to issues with theitem¡®s content¡° Anyone knowing an alternate source?
