shorted zener - how to find voltage
I'm working on an old NAD receiver (7240PE) that has a shorted zener diode in the power amp section. How can I figure out what voltage to replace it with?
Just in case somebody out there actually has a schematic, it's D434.

Just in case somebody out there actually has a schematic, it's D434. Any markings on it? What is the voltage rating of the following filter capacitors? What is its regulated voltage feeding current to? Tom |
