The problem with tubes is the tubes! Fifteen years ago I went wild on an ARC SP6 and had it on two chassis and voiced the thing around Sylvania ladder plate/rectangular Getter 12AX7s and Brimar 6DJ8s.....It was a wonderful unit, but the only thing stock was the circuit board.....I had enough tubes to just get into trouble and had folks searching all over the place for the Sylvanias and only found a couple more at that time.....I had to sell the unit and bought an SP-11 and that stayed stock for almost three weeks before it was rewired and recapped....I sold it in a year or so and keep my hopped up ARC SP3A-1 in the garage for comparisons and have gone all solid state.....The point is it is hard to find good NOS tubes and lots of folks would go SS just to forget the hassles of buying good tubes....
From tubes to solid state
Who has gone from tubes back to solid state, and why?
