What are the symptoms with the QS amps that make you certain they are kaput?
How Long Should a First Watt SIT3 Last ?
I'm fairly certain my Quicksilver Monos are kaput. Im thinking maybe I don't want to mess with the troubles and uncertainties of tubes. Im considering getting a used SIT3, but how long should they Last considering the internals are no long available if I encounter a problem?
Thank you,
TD
