Re: Tube life

The 6L6 is part of the high voltage regulation circuit and the 5AR4 is the rectifier. Neither of these tubes will contribute to signal "tube rush". 5AR4 tubes can last a very long time. The 6L6 wil also last a long time in this circuit.

If the previous owner left the unit on all the time or a lot of the time, the signal (6H30) tubes may well be used up.
