SOURCE: Noisy channel of receiver
Generally, crackling noises come from anyplace there is a mechancial connection for the sound signal. The volume control, main/remote speaker switch and possibly the headphone jack. That is where the contacts must be cleaned, but it requires dissassembly. Try operating the main/remote speaker switches, and plug/unplug a headphone several times. I am assuming there is still audio behind that crackling. Are you using both main and remote speakers simultaneously?

This happens on mine also. My theory is a relay. If you turn the volume up (Waaay up) momentarily, you "burn through" the oxidation on the relay and the sound comes back - for awhile. Some day, I'll get in there and replace it with something more robust.

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.
