Hi yalazogeday

Your amp is fitted with two 2SD588A (NPN) and two 2SB618A (PNP) power transistors in the output stages. Click on the part for a place to get them from. These parts are no longer available from Pioneer, nor are the prescribed replacements. (the amp was built in 1978) Because of the unusual transistor package used, you may have to upgrade to a more modern transistor, and modify the mounting also.

    Hey there,

    My amp is the sa-9500II and it clicks off periodically. Is that caps or transistors in your estimation? If so is a full cap replacement the only method here or is there a know cap you'd target? Thanks

How do I fix my problem I m having with my pioneer sa-1510 amplifier

You simply have a bad solder joint somewhere. A visual examination of the solder joints should show you the problem.

Dave , If that fuse is blowing , there is a problem in the power supply or output section. If you have a meter that can test diodes / transistors. please check the output transistors first. Most likely one or more are shorted. If they check ok , you should check the power supply diodes .You can order new ones from a number of online stores by simply putting the part number into google. Hope this helps ?

I have an pioneer SA-510 amplifier and i want to know how to connect it to my laptop and what kind of aux i need ? plz help

Just go to Radio Shack and buy a 1/8 male stereo cable and the other end with 2 male RCA plugs and connect them to the AUX or CD input of your receiver, the 1/8 male connector goes to your earphones output of your laptop, hope it helps.

Pyramid music

There's a cable with one side for the earphones out of your laptop, which has to be 1/8 with 3 rings, one "L", next "R" and "Ground", on the other side you should have two RCA male connectors, one white which is the left side and one red which corresponds to the right side and this end goes to CD or AUX input of your receiver, this cable should be at Radio Shack Store, hope this helps.

Pioneer model SA 9500 stereo amplifier problems.

Is the dc voltage reading on the base of the outputs 0.6 with emitters reading 0.014 or there about. Depending on the outputs used you might read 1.2volts on the base. Your collectors will read the power supply voltage of 50 or 60volts or more. If this is what you are reading on your meter the problem is in the speaker protection circuit. This circuit is what drives the relay you tested.

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.
