I have an VTA St70 and like it very much.
It is with SS rectifier, 6GU7 as input tube and 6CG7 as splitter tubes.
The power tubes are EL34.
Now I want to try the 6L6GC tubes. I have read, this is not a problem, it will work.
But if I would like to get the best conditions for the 6L6GC, what would I have to change?
Bias setting is enough?
Enjoy your weekend
