Quicksilver amp owners

I've owned the 8417s and the V4s. They were mighty fine amps. One thing you will notice that is that many QS owners seem to be pretty loyal to the brand, among other reasons they tend not to breakdown.

You might want to try the NOS Siemens EL34s from RAM Labs. They are much better than current production according to most listeners. They are also very long lasting. I use them in my RM9 SE amp and preferred them to the KT88 Reissues with my speakers. I'm not sure how hard QS is on tubes, depends on bias setting as well, but these Siemens are expected at least 10,000 hours on my amp - that is a lot of listening.
