I purchased a new set of GL KT-77’s for my Had Inspire. At about 50 hours one let go damaging the amp. The exploding capacitor made quite a pop. It took me about 2 hours and 10 Q-Tips to clean out the mess. Dennis replaced the cap and the connector strip that broke from the explosion. I’m not a Quick Silver owner yet but I’m looking hard at the KT’s. Check with Hilde45 as he has a pair and experiments a lot. I have tried about a dozen power tubes in my amp. I have NOS GEC and SED and Tungsol , I like them all. I’ve run modern GL, JJ, EH , Psvane and Tungsol. My extensive testing and spending left me with this conclusion. Get the best NOS input and driver tubes you can afford and run modern power tubes. I prefer the Tungsol KT -150, and KT - 120’s. I had the similar results with reproduction Dynaco MK III’s.

Tube suggestion for Quicksilver Mid Mono Blocks
After switching from KT88's to E34's (with which I had a mishap), I installed GL KT77's and they are doing quite well.
I just posted 2 sets of KT88's for sale on Audiogon (A matched quad GL, and a matched JJ quad).
Im thinking of getting a set of GL KT66's for rolling.
Anyone have comments on the differences between the KT77's and the KT66's, and what happened to the 6L6? And maybe a comparison between the 6L6 and the KT66.
Thanks
