[QUOTE="Llew, post: 740019, member: 175007"] I needed a circuit diagram for the power supply section of the TD, but unhappily it's not available anywhere AFAIK. Even the guys on the official TD forum don't have one. Only thing for it was to trace the existing circuitry on the board. I had a spare TD which had a PS which had suffered catastrophic failure - the chopper FET had shorted and taken with it the current mode controller IC, plus transistors and various diodes and resistors. As it necessitated a rebuild, the opportunity arose to be able to (fairly) easily trace the wiring routes and component values with the damaged components removed. Only the secondary circuitry is shown here; this may help in identifying vulnerable components, e.g electrolytics. I'm still drawing out the primary, which I will add later. [/QUOTE]
