WARNING: Working on amplifiers is very dangerous, take extreme caution. Follow at your own risk.
Meter Bulbs, Capacitors And Fan
First it was the meter bulbs that burned out, then the amp started making a popping noise. After fixing those items finally the fan began to make noise.
I have it together now and back on the air.
See my website for all of the details: www.k0pir.us/ameritron-al-811-...
UPDATE: I eventually had to replaced one of the bleeder resistors.
