Recommendations for retubing my CCV

[Nigel]

I don't have a CCV unfortunately but wanted to chime in before everyone bashes JJs. Been putting JJ in my Splawn to experiment a bit. Their pre's are very decent for new production. Zero microphonics. Little on the dark side but great for bright maps. For power tubes try EL34 II's and EL34L's. I like both. Purchasing from Eurotubes after years of bashing that store.

That said, I'm currently running some Chinese square getter 12AX7's I bought off of @just42dave - and really like them. He even threw in some 'candy'. Give him a shot

PS: and yes, the =C= EL34s I got from @Laura a long time ago - still work fine, and tonally similar to JJ if that is even perceptible.

JJ KT77 is superior to both as it is the finest EL34 type available. I agree with Bob Gjika on this. Furthermore they come alive at 25 watts idle AND at over 500v B+ (550 ideal!) so the CCV is a perfect circuit for them!

The other big problem with late winged c is a lot of the tubes test high for current draw. Their EL34 was notorious for that.

Low plate (AND SCREEN!!!) current draw are preferred as high current draw tubes are weak.
