Technics ST-Z45L Tuner Repair

Описание: The repair of a Technics ST-Z45L (circa 1982) tuner. Warning this is for Electronic Engineers and competent technicians only – Very Exposed Mains Voltage! However, I found it a reasonably easy repair and (albeit for another model) managed to find a downloadable circuit diagram.

Notes:
The 2 Gold Super Caps are connected in series and when fully charged should be about 4.5VDC.
My added small heatsink and replacement transistor (Q701) mustn't be physically too high above the board – will short out when the case top is fitted!
Once finished, the very small hole I drilled on the back of the main's switch can be covered by electrical tape.
