Quicksilver V4 tubes

KT 77 Gold lions sound best kind of a mix between a kt88 and el34  and I would look into buying nos smaller input tubes , when was the last time they were replaced ?  Old tubes can still work but loose lots of detail over time 

Brent Jesse recordings , or vintage tube services.

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.

Vlad47,

I don't know your amp, and have no idea if KT120s or KT150s will work. I believe that The Tube Store has them in stock, but your should check current stock.

+1 on this suggestion. This is what I used in my QS V4 amps when I owned them

My favorite tubes when I had my balanced V4’s were Ei KT90’s and GE 6L6GC’s. The 90’s were more powerful than the 6L6’s but the vocals with the 6L6’s were outstanding. My audio dealer likes KT 77’s in there now and he’s not a fan of the 150’s. The V4’s are the only amplifiers that I regret selling. Good Luck!
