Need values (part numbers) of electronic parts

I have a Technics SA-828 receiver that has worked for about 28 years. Yesterday it quit working, I smelled something burning, and noticed when the sound quit the red protection light went on. I took off the cover and noticed on the circuit board with the large capacitors that 2 diodes and 1 thermistor (I think thats what it is) were black and burned. I read on another electronics website that the protection circuit is on this board also, which makes sense, hence the burned out parts. My problem is I do not know the values of the diodes or thermistor or what ever it is. the positions on the boad for the diodes are marked D617 and D621 and the thermistor? is TH601. Does anyone have a service manual so I can buy these parts? It's been a great receiver. Thanks


Send your unit or call Hi-Tech Audio for a quote for repair. Very reasonable , top notch repairs. I suspect there is another issue that made parts burn up. PH# 503-618-7605. His name is Rolland , Gresham ,OR. Regards Karl
