There are poor solder connections at the output amp pacs and the voltage regulators. Once these are resoldered the problem should go away. If you can solder, resolder any connections that appear grainy or have rings. If you can not, this should be effectively a labor only repair for any shop that works on audio gear.

I too have a Technics SA-GX100 and it's rated at 2 x 40W @ 8 Ohms. I have the Technics SB-2840 floor model speakers hooked to it, which are rated at 200W Music Input - 8 ohms. It sounds very nice just to be a 40W receiver.

An amplifier should never be turn on without speakers, it will overload internally.
make sure speakers work and try again.
