Power Tubes Quicksilver Mid Mino

Just picked up a up Quicksilver Mid Mono along with 6 Mullard XF1 EL34’s. The tubestest surprisingly strong, but I want to extend thier life as long as possible and also try a different Tube Type. Any comments on the Gold Lion KT77 or KT66’s in the mid monos?  I’m using a fairly efficient pair of Audio Note AN/Es, so I don’t think I need KT88’s or KT120’s.  I’m running my exogal DAC striaghf into the amps.  Great combo.  Haven’t felt the need for an active pre.  Thanks.

@oddiofyl I use new Tung Sol 7581A in my EICO monoblocs. Awesome. Great bass and clear clean highs. Search for my post on these in another thread.

I'm a fan of GL KT88s and have used them for years here and there. However, the Gold Lion KT77s, at least in my single ended amp, are amazingly better sounding than any other tubes I've used in this amp, including KT120s, 88s, and 150s...I was surprised by this as I had tried a pair of JJ KT77s and they sounded not so good, but they're a completely different tube...now on my second  pair of the GL KT77s, and man...a great tube.

The new Mid Monos apparently have separate bias for each tube and can take KT120 and KT150....  i asked Mike from Quicksilver a while back if KT90 were ok and he recommended against using them...   He said that they were voiced with EL34 and he recommended EL34 .   When I bought my Mids, they had big bottle 6l6 and they were ok,  but I didn't know how many hours were on them so I installed EH EL34 , the ones with the green label. They actually sounded really good.   

So if you have the older style with single bias pot and L.E.D. I would call or email QS to see what they caution agai st using.
