Gentlemen; I have a Heath SB-1000 amp which is giving me some trouble.
The 7.5 volt Zener has gone bad, along with some components on the meter
board. Someone had sent me information years ago about substituting 10 1
amp rectifying diodes in place of the Zener. Does anyone have experience
with this mod. Unfortunately I didn't save the original notes. Thanks.
