Tubes for the Quicksilver mid mon.
After having these new to me amps for about a month I think found a good tube combination. (Note this a comparison of tubes on hand)
Input and driver tubes
EI pre war 12ax7. More tightly focused than a Telefunken pair labelled the Fisher. Much better that a pair of new construction PASVANE T series version 3. They sounded a little grainy, but to fair they have no time on them, so I assume they’ll smooth out
ECC83. Amperex. Great mids and a real sense of drive.Better than any Mullard pair.
Mullard fx1 el34’s. Only compared them to a quad older Svetlana Winged C’s. It worrth noting Thant I haven’t tested them to get better matched pairs.
Ill be purchasing a quad off new construction tubes either gold lion K66 or some chimes KT88’s.
Any have ave any other combos that work well, especially those featuring new construction output tubes.
