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

Hi,

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.

regards
Swamy

SOURCE: Technics SA-DX950 intermitently sounds blown out

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.

Checked fuses then sprayed contact cleaner on the fuses and the fuse holders. The speakers began to work correctly.

SOURCE: Max. wattage for speakers w/ Technics Receiver SA-GX100?

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.

Why is my centre speaker not working on my stereo setting on phono?


Records are binaural only. There are only two channels of information, left and right. There is no signal available for a center channel.

Technics SA-AX530 all modes not working - no sound


Not a good sign. There should be a click a few seconds after you turn on the unit. That says the output section is OK. If there is no click, you need repair. Perhaps only some fuses inside, but it could be worse.

Also make sure that the speaker switch is in the right position, like A, not A+B. Also the headphone jack can silence the speaker.
Make sure that ALL switches are in the right position.

No sound from left channel on my Technics SA-R 230


May just be bad connections on the speaker relay. Flip the main board over, and check those connections. It is pretty common on these older models.

Technics sa-dx1050 overload


if any one of the channels was shorted out, even momentarily, that channel's output transistors would likely be blown causing it to stay in protection mode. (or overload as you put it). Time to visit the repair shop.

Technics SA-DA10 Receiver-no sound


Most of these problems are rooted in a failed power amp module.
I'm working on an older technics unit but with the same troubles.
