I have recently acquired a TC Electronic D.Two which has a PSU problem and it keeps on blowing fuses. Having built a lot of gear from this superb forum I was happy enough to open the enclosure to see what is or was going on. The switching FET 2SK1637 has blown but whether it finally gave up in its own right, or something else pushed it over the edge I don't know yet.
Generally the other components appear visually fine with no obvious signs of overheating and the PCB tracks are not damaged either. In any case it would seem sensible for me to replace some of the caps with new ones. I have looked to buy the FET but there is more than one variant (2 ohm or 3,3 ohm being one of the parameters that spring to mind).
If anyone could advise me which FET it is, it would be helpful. If anyone has any experience of these PSU's and can offer any other advice I would be most grateful.
Thanks
