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: Technics sa-g78 no sound from front speakers

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.

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.

SOURCE: My Technics AV Control Receiver SA AX530 is in overload

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

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.

I have a vintage technics receiver, model numbe 5360. i would like to the watts per chanel.


Full specs. But take them with as grain of salt because they don't specify the bandwidth or distortion, plus they use 4-ohms as the load instead of the 8-ohm standard. Avoid driving any amplifier harder than it is designed to go because distortion rises rapidly and it WILL kill itself or the speakers if overdriven.

I have a technics sa-ax7 receiver and have sudenly lost sound on the right hand speakers.can they still be repaired. What could be the problem. Thanks


1). Look for a blown fuse on back - or inside. I had this similar problem with a Technics SA 5060 (vintage) receiver, and there were 2 separate fuses for left and right channels. One may be blown.
2). Try switching speakers (physically switch the left and right input plugs in their jacks - or wires if no jacks. If the left speaker doesn't work now, there is an issue with the speaker that has no sound. Run an ohm meter on these speakers as well to check them. There should be 8 ohms approximately. If no reading, then your apeaker is probably blown. If you can see a short on ohm meter 0 ohms) then you have a short circuit in your speaker.

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.
