Further checks on this PSU reveal that HT+ at 450v and 200v or so are present at the Smoothing Capacitors, and 200v is present at the Transformer primary, but the voltage present on the two A13TA power/switching transistors quickly decays to a very low figure. Unless this is due to the effect of a high frequency ciruit on my DMM, which I doubt, there is still a fault present, but at the moment I'm not sure what it is. The circuit is virtually identical to that of the PavoUK ATX PSU linked to in post #27 by cmjones01(Thank's, Chris)
