Could be a lot of things. More triage is needed.

Have you done any isolation to prove/disprove a certain source, channel cable or speaker are NOT the problem first?

Need service manual for pioneer sa-600


Head straight to the (European) electrotanya website, which offers free downloads of a wide range of service manuals. No registration is required either.

The Pioneer SA-600 schematic shows both voltages and currents. For this amp, the total current for left & right output modules (no signal) is 60mA. No-load voltage is 58 volts, dropping to 48 volts (one channel driven, 25 watts out).

Pioneer VSX-21 Elite: Issue: after playing music softly for about 1 minute the machine goes into "overload" mode. Unplugging will reset this. Keeps going into this overload mode, acts like...


Check to see if the unit is getting unusually hot.
If it is, check the impedance of the speakers and speaker wires to make sure they aren't shorted, or close to shorted (ie - partially blown speaker).
Try running the unit with the speakers detatched to see if it still happens.
If the unit gets hot with no speakers and goes into overload, then we need to start checking the components inside.
Look for electrolytic capacitors that are bulged at the top, or that have discolored the circuit board at their base (leaking).
Any caps doing this will need to be replaced, and will likely solve the issue.
If there aren't any, or if that doesn't solve the issue, start checking the transistors at the output.
Look to see if there is a DC voltage riding on them, and make sure they aren't shorted out.
If the power amp is a hybrid chip, see if you can find one cheap and replace it if you can't see anything else wrong, or if one of the hybrids is overheating a lot.

I have an elderly (but until now totally reliable) SA-620 amplifier. All of a sudden the left channel isn't working. It is the same whether you use the A or B outlets. Any ideas as to how I can fix this?


You do not mention whether you use one or several inputs on the SA620, but move the selector switch to & fro a few times to clean its contacts. Similarly, unpIug the phono plugs & replug (on Left channel). I aIso assume there is no left channel when using headphones. Also check the two thick wire links at the back are pushed in properly (take out & push back in to make sure), since these link the preamp to the power amp. All the above is done with mains power off.

On these old units, switches sometimes fail due to impurities on their contacts, so operate them all (with mains OFF) a few times to wipe the contacts clean.

It would be informative to find out if the fault is in the preamp or power amplifier section.
To do this, connect signal (eg external CD) to the TAPE 1 'PLAY' input (left) & switch front panel to TAPE 1. This bypasses the preamp section & injects the signal into the volume control. If there is still no left- hand channel, then the fault is likely to be in the power amplifier.


Only if you are technically competent, disconnect SA620 from mains, remove the SA620 lid, and with an insulated object eg a plastic screwdriver handle, tap the loudspeaker relay RL1 to release a possible sticking contact. If this does not cure the fault, then the same can be done with the unit turned on & a signal present.

If there is still no response, further fault finding in the power amp will be req'd.

Connectivity


you have to make sure you are on the theater mode on your amp. that's the only time that the center speaker works

I have a 700 watt 2 channel amp (pioneer) that stops the whole sterio when the right and left sides are bolth hooked up at the same time. what is wrong? i thought the hookup was pretty much idiot proof. is...


One possible scenerio is one of your RCA's is pinched real bad. I mean you drilled a screw thru the RCA and its grounding out and shorting out.

2nd possible Scenerio is you connected on the back of the radio the rca to the input instead of the output. You have to hook up OUTPUT OF THE RADIO TO THE INPUT OF THE AMP. Any other way its wrong.

Stereo switch kills right channel


Do you mean a 5 pin Din plug?
What I would do first is take the cover off and with the amp powered up (Din cable not plugged in) locate the point where the Din Cable goes in. Then with a screwdriver and your finger touching the metal part of it, touch the terminals of the socket. You should here a buzz on either channel. If you do here a buzz of the same level, then the amp is good and your cable is faulty.
If not then a fault has occurred, you can determine where by the same test as above following the circuit of the faulty channel. Remember right & left channels will have the same sets of parts. So if it buzz's in the good channel it should in the same point on the other.
I ask about Din plugs because they can easily break and can be wired wrong too!
PS DON'T put your screwdriver near any power sections! And don't let it short something by the blade touching two areas at once!

Old Pioneer SA 700 amp- only left channel works. It will play all inputs- tuner, turntable, etc, but right channel will play none. What's the likely problem? If I can buy the part, I'm not a pro, but I'll...


I have one of these exact amps, more than likely its the volume pot that will need a clean with some WD40 to clean the dust build up inside, try putting the balance on that channel alone and turn the volume up, if the sound kicks in or trys to kick in, this will be the problem or the track inside the pot maybe very worn on the lower setting, which will need then replacing, remember these amps are around 40 years old and chances are it has done a lot of work, if this doesn't fix the problem, as the previous post said it may be in the power amp section and could just be a dry joint on any of the componets, you can pick up all the componet parts fairly easily and cheaply nowdays anyway, let me know how you go.

I have a Pioneer SA 1050. All the lights come on


check your speaker selector switch to see if its on the correct setting ie; speakers one ( not speakers 2 ) also check your speaker cables by reversing them, ie; put right speaker cable into left channel and vice versa with the left etc? check also to see if your amp is set to headphone output by mistake in which case no sound will come out until you select the speakers instead? good luck.

Hook up pioneer stereo amplifier model SA-1270


for audio system always you have left and right channels.
get the output (left&right) from tuner---go to equalizer input left&right.---from equalizer output go to amplifier inputs.and certainly from amplifier output to speaker.
