Noisy channel of receiver

Hi,

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.

Thanks,
Nancy

    Thanks Nilrem. I did dis assemble tonight. This is not your dust in the volume control thing although it sounds like that. It happens on it's own, even when the volume is down. I switched the left speaker cable into the right inputs and it still is static-y. I have been having problems with the right speaker's input on the back because it is an ancient speaker but the right speaker in the bedroom has the same static. It sounds like a radio that is not set on a station but it's only in the right channels.

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?

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.

The volume gets noisy, cracking sounds and fades out


Your volume control is dirty. Apply some deoxit or wd40 directly onto the module.

Fan quit working. Is it likely the board, or the fan? Currently have a Radio Shack fan mounted; it's 120v, plugged into the AUX power on the back of the unit. It's noisy, otherwise unit works and runs...


Hi, Have got and still use a Technics SA-GX910 Dolby Amp. It had an overheating problem too due to Air temp and power drain etc and the internal fan only engaged at certain volume level. Overheating was overcome by adding another internal fan.
Your unit however might need a bit more of a fix-me-up or throw it away

My technics sa-ex 300 wont power up it keeps saying over load can i fix it?


Unplug the speakers and try it again. If it still does it then one amp channel is probably blown

If it stops then the speaker is faulty or wire may be shorting

The sound is distorted and overwhelmed by static


Depends what the real problem is.

Is it related to certain sources only - try new or reseated cables,swap it to a different input; single channel - swap to isolate; or certain controls that have become noisy? A shop might be able to get some tuner cleaner into them.

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.

Center speaker is dead or what it can be on my Technics SA-dx930.


More than like, the center channel is turned off on your receiver. Please see page 16 of the manual, which is located here:
http://service.us.panasonic.com/OPERMANPDF/SADX930.PDF

The manual says to do this:
Turn on the receiver.
Press Speaker A and B button at the same time.
The word Setting appears then changes to Front
Press A to select Center
Press B to choose Large, Small or None for your center speaker.
After choosing Large or Small, press A again till you see Complete on the screen.

If this helps, please rate my response.

Look for lossing solders points or bad conections. Start to look on those components of hi wattage and components to get hot alot, those are the most common to have weak solders spots.
Also some equipment need to be clean because the dust can make problems.
good luk.
