Better check with Mike Sanders. Not all transformers are rated for that much power. And some amps are designed for specific tubes, or at least tube types.
Quicksilver V4 tubes
My monoblocks are from 2006 and I'm looking to retube them I've had the KT 88s in them and now I'm running EL34's but would like to go back to a more powerful tube such as maybe the KT150 would like some suggestions
