In Reply to: Yes but look at the plate and screen voltage compared to maximum ratings posted by Russ57 on June 16, 2005 at 11:13:45:
hi russ,
I don't think VTL uses "standard" = metal type 6L6 which indeed are rated @ 360V plate & 270V screen grid.
glass type 6L6GC are rated @ 500V plate & 450V screen grid, so this is a prime example of operating a tube well below it's published max. ratings.
so where's the problem ?
