How to restart tube amp and pre in boxes for 2yrs

Ya sorry bout that..I shouldn't post on pain meds...I do stand corrected..

What I was meaning to say was that at low AC voltage when using a variac, when the circuit initially gets energized, current can peak. That varies depending on circuit topology, solid state vs. tubes etc. That is all.

TKS you all i listen to music last night for the first time in a long time. Now getting my turntable put together but i wont expect anyone here to walk me through it......lol Happy listening Daniel

Running a tube amp for any length of time without output tubes installed, as Hifigeek suggests, can be very dangerous. The reduced current draw in the power supply will cause the B+ voltage to shoot up considerably, and may exceed the capacitor maximum voltage rating. On an older amp with marginal capacitors, this greatly increases the risk of capacitor failure. The Variac idea is a good one, but leave the tubes in place, or monitor the voltage on the capacitors to make sure it stays below their rated voltage.

Indeed Selectric, I even monitor AC ripple as I'm bringing the voltage up and carefully touch the caps to make sure they're not heating up!
