gm70 vs 212!

Paul,

Have been waiting till Chris V finishes his 212E amp to ask him for the same test, but looks like you are faster. My own project is GM70/304tl based but I make everything ready for 212 as well. Why not the same 7k for both tubes and equlaizing the power by volume control? I'd go for 10k after few nights spent over the STC curves.

Yes, the other GM70 is graphite. For Cu ones decrease the max power to 100W.

Would love to hear the results !
