I recently purchased a kit amp from the Far East. It's a low powered valve amp, for which I ( conveniently ) already have a couple of sets of replacements of higher quality. I 'reasoned' that I couldn't buy the transformers and chassis for less elsewhere, so went ahead. Woo!. It's a valve rectified stereo amp with a 6n2p driving a pair of 6p1p outputs to a heady, probably, 1 Watt. More than enough for near field use with my computer. The vendor sent across the layout and schematic, and a few things concern me. 1) Coming off the rectifiers, the first capacitor is a 220uF. This seems somewhat high!. It strikes me as being too high a value by a factor of 10ish and a 22~33uF would give the rectifier an easier time. 2) Parallel resistors? Why? Other than cost reasons, wouldn't a 120R10W do the same job? I'm also thinking a resistor ahead of the first smoothing cap might help the rectifiers. I may just use solid state for the rectification anyway, and power the heaters for show in which case, I'd need to drop the voltage further, and the large first cap wouldn't matter so much. 3) In the rectifier section, I'm looking at it and I'm thinking there should probably be a pair of 1N4007 between the two 240V outputs and the HT centre tap. 4) Other than, including postage, I couldn't even buy the three transformers, I went with this as it looks like it'd be fairly easy to rework it to run with 6p14p valves in the output and possibly a 6n4, or rework the socket and use a 12AX7 as the driver. So, have I lost the plot?, I have a nagging feeling I've missed something blindingly obvious here. I know my voltages will be a little on the high side as the transformer is a 230V input, and my wall voltage usually runs at 245V. All clue gratefully received. I have been struck with a case of the dum-dums.
