Question about Audio Players & Recorders
I have an old Technics SA-300 receiver. The right channel has become very noisy and crackly. I have two sets of speakers hooked up to it and both right speakers are the same, so I know it's the channel. I blasted the speaker inputs with contact clean and disconnected the mixer, tape deck, etc. The noise is still there.
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?
