Thank You for Your reply...
In the beginning when I wanted to make some SE "monster" I go gor GM70 choice, but there is so difficult getting two of GM70, and then i go to second choice - GK71, that's because i already have these tubes. But I don't think that GK71 is analog to GM70... even in triode use...
The polish link I know from before, but the other is new to me, but thank You for the links ...

The question is remain the same- the sheme with GK71 in SE
maybe with 6c33c or gu50 - driver... I don't know yet...
any suggestions are necessary and welcome!
