Hi All,
I have been given a 40 year old Technics SU-C04 amplifier that blows fuses.
I desoldered the 4 power transistors and discovered the D718 (PNP) and B688 (NPN) were shorted.
These don't appear to readily available so I'm looking for substitute suggestions. I'd obviously replace all four so they would be matched pairs.
I've attached a picture of the transistors attached to their heatsink. Because of, what appears to be, overspill of heat compound, i'm guessing the transistors are not original.
I've also attached the service manual.
Thanks in anticipation.
