Turned back tube amplifier quickly is the possibility of destroying!

High voltage amplifiers (as 211) often has voltage doubler circuit, (sometimes built with SS rectifiers). If the constructions does not contain HT delay circuit, the quick turn back possibly causes catastrophe (HT immediately presents, because HT PSU capacitors is fully charged).
