As my Triwatt has the newer output transformer with the second primary tapping for running EL34s, is there any reason I shouldn't fit a double pole switch to allow switching to bigger bottles without needing to solder anything? I can't currently envisage needing more power than I get with the 6V6s, but have in he past run both a 50W Marshall 1987 (with a PPIMV mod) and even a 100W JCM2000. In the good old days when it was easier to clear up at then end of the night if you'd laminated to crowd to the back wall ;)

Going from memory, I believe for running EL34s, more is required than just changing the OT secondaries... Not 100% sure, but I think there are some changes required for the bias circuit... in which case, making it switchable would be more involved. Again, that's from memory, so consult the build guide to be sure.
