I love Princeton Reverbs…who wouldn’t? 🙂
This one; from the Silverface years. The bias filter cap was bad, which caused the output (power) tubes to be biased incorrectly, way too hot. Hard to tell how long it has been in this condition but the output tubes are bad, probably because they were running so hot for a long time.
Anyhow, this one needs a new bias filter cap, new output tubes and I think it would be wise to install new power supply filter capacitors since one important cap has already died.
It gives me a real sense of pleasure to bring these great amps back to life and working at 100% !
