Re: Power distribution, was: 2-wire, unpolarized outlet ?

Nick There are many who feel as you do.??
I would check the tube heater voltage at the tube socket.? If it is within 10% of 6.3 volts then all is OK according to the vacuum tube manuals.? I am of the opinion that heat is the real enemy of reliability, not line voltage.? The cooler the chassis is, the longer the tubes (and everything else) will last.? For this reason, I advocate replacing tube rectifiers with silicon.? Less heat is good, a bit higher B+ doesn't mean a thing but a cooler running power transformer does.
Just like with lightbulbs, it is the ON/OFF cycling that is the vacuum tube killer. Jim

I always use a variac on my vintage gear set to about 115V to keep the filaments safe.? My line V is about 121/242 but at a previous residence it was sitting around 108V!
I still hear people say "220" when they mean 240V.? I've also heard "house current" and "mains power".
Go to the EU and you'll find 230V, 50Hz (UK is/was 240V), and of course those funky outlets.
