Question about Audio & Video Receivers
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?

SOURCE: left channel not working
Thanks, yesterday i tried changing the speakers from right to left, the problem still remained on the speaker getting connected to the right channel. Later i pulled out the speaker wires from the reciver's end for the right channel, cut them and pulled out new strings from the insulation, twisted them and inserted, the speaker is working fine, though not 100% but close to left channel. I guess the problem was old strings in the wire which had got over twisted and were not parallel to each other.

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.
