I have a nearly new matched set of KT-150’s sitting on the shelf. Having moved to a much smaller room I actually prefer the smaller EL34’s in my PrimaLuna amp. I believe they’re still available new. Just a bit more costly than they’ve always been.
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
