I've got myself some 6sl7's to try out so I'm going to mod my experimenter amp to accept these rather than 12a*7... I also ended up with some 12sl7's - can the 12v filament be run on a 6v supply? I understand that these tubes are a bit different than 12a*7 types - no filament tap... what are the limiting factors running a 12v filament tube on a 6v supply - runaway current consumption or something?

is this thing on???
this is really more for curiosity's sake... if I run a 12 volt filament tube in a 6 volt filament supply, what would happen or not happen?
I could easily use these in another project with a PT w/12v supply... but... I'm curious. The only info I could find out there on this topic was "don't do it" but with no explanation... -
I'll take a wild guess and say low emission from the cathode. You won't have enough electrons free in the tube to conduct.-MikeComment

That makes sense... tube doesn't heat up, the "valve" doesn't open - so it would either sound like scat or not at all... would this state have an effect on the PT?Comment

The filament *may* glow a little, but you're likely to hear nothing.Comment
