[QUOTE="Ampdog, post: 45742, member: 144"] As far as I can recall the power transformer is either 110V or 230V - wish I took notes before. Or you will be able to trace two primaries wired in series, but that was not the case in the one I serviced. Yes, they are running without an earth lead, but it is easy enough to fit a 3-core lead. Regarding power supply capacitors I was able to fit JJ 50 + 50?F/500V caps available from Mrs. Valve, but they are expensive. The cathode bias cap(s) were fitted underneath. (For better music power output, I used 2200?F 25V types; they are quite small.) And I also split the single EL84 cathode bias resistor. It is rather stupid to take economy as far as saving one extra resistor there! [/QUOTE]
