Thanks for the schematic links Andy, the first will surely be very similar to what I have. The manual for the similar model is here: http://www.electrojumble.org.uk/DATA_2/APT_504.pdf but it is for a more complicated version but very simiar in many ways. Ed, the selenium rectifiers will surely provide a degree of protection - lol.
