Hi all, Just an update, we got the fan job done in my friends AL-80B amp. All is well.
I never noticed that the neither?of the meter lights work. The amp is already? put in it's place so it is a small "project" to get it out. Anyway, the schematic?that I found on line does not show the meter lights and unless I missed it, it doesn't list lights on the parts list either.
Does anyone know where the meter light voltage is picked up from and what is the bulb/lamp voltage?
If I can get this information ahead of time, I can get some LED's ready so we can pull out the amp, install the LED's and back together again.
