Re: Lower Purity W: Good? Bad? Neither?

I was thinking about the same thing...

My C-J came with Sovtek 6SN7GT's. If this is what they designed their amp for, then it explains why the filament fuse tended to blow out; and the filament supply does look more aged than it should after couple years of use. Maybe the lower cold resistance of NOS tubes do put more stress on the filament circuit? Agree? Disagree?
