Thx for the fast reply...two questions:
1. In the current setup it is a positive +15V supply. Ate you saying I need to change it to -15V ?
2. Why 15 ? Why not 12 or 20 ? From where does this number come from ? Note that a 6n6 generates at 8ma -7.5v Ug while a 6922 would generate -4.1V Ug with the same current and 300v. I prefer the 6922 over the 6n6, more life-like.
Thx a lot.
Frank
