Quicksilver amp owners

just purchased the M100,uses KT88,love the sound especially the mid range,very open and seductive the highs are very smooth, bass is tight and deep, love the sound,use to run Belles 350A ref SS awesome amp, but it was just too powerful for my condo, Question: besides the KT88 witch other tubes are compatible with this amps, and witch brand should I try; also drivers, and rectifiers tubes witch are the best you have try:

Pulled out the KT-88's and tried some SED El-34's.

Much better voices,this is a great tube for the Quickies.

Richness now, that was missing with Lions,everything else great too.
Nice dynamics as well. 3D liquid sound.
These will stay in for awhile...

Wow, these are fun amps! I can use all my power tubes I have bought for other amps I've had/tried. No waste.

Every tube I tried with the Quicksilvers sounds good,some just better,no bummers though.

i don't like current production tubes. i do like mullard el 34s. perhaps, the original gold lion kt88 would be better, as opposed to the replacement.

what about my suggestion for replacing the caps and resistors, as well ?

I know nothing about replacing parts,I do have some PIO caps in my ASL 1003DT integrated and its a keeper.

I personally don't think the Quicksilvers lack, so I wouldn't change anything.
Maybe talk to Mike about oil caps,I would be interested in hearing his response.

You think he would have experimented with them in his designs.

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.
