900 slx trouble

[JC@]

Is transistor TR1, A13, the same as MPS-A13 ?
In a jcm 900 SLX I'm getting no voltage reading in that area, btw
Right after R35 and R36 I get no voltage reding; both zeners are ok. I have not checked IC1 and IC2 yet.

MPSA13, yes.

You get no reading across the zeners? Or you get zero volts? Are those resistors open?

If the zeners were shorted, or the caps across them, then those two resistors would get blazing hot. If the zeners measure OK in circuit, then the caps in parallel won;t be shorted either.

Enzo, the TL072 was shorted. Thanks
