Pioneer SX-203 power transformer ATS1526 secondary voltage???

Looking for the secondary voltage from the power transformer does anyone know what it is? 12VAC 24VAC???

    For the main power tranformer you are probably looking at around 50-70volts AC on the secondary. and around +and - 40volts DC after the rectifier diodes. Where are you taking the measurements? What problems does it have?

Just a question.1st.. if you don't know what you should have... then what are you going to do... if it's lower or higher ... seems like you should have a print before you go looking...go check at the off and on switch for the standby .. 9v more or less to trip the relay to turn the sys. on... now get a print...or go backwards to the transformer to see if it's blown. or something in between is open

Reddy heater pro 110


check that power is getting to the transformer, if so test the transformer for continuity. if it is good look for a short in the high voltage(spark plug) wire, and that one side of the secondary is connected firmly to the chassis of the heater. if no power to the transformer then trace the wiring to find the defect.

I want to know what is the secondary voltage of transformer inside PC control panel ?


You have not mentioned the details of the machine in question. All you need is to check on the LT ( low voltage side ) of the transformer to find the secondary voltage which will be about 20 to 30 % less than the DC voltage shown on the capacitor on the board. If there are more windings then you can get the primary rewound without any changes to the secondary that must help to solve.

Put to big of a fuse in my pioneer sx-203 and burt out a cucit


Using a higher voltage fuse is not a problem, but if the fuse you used amps are to high, that is a problem. Sounds like a resister burnt. You have a short somewhere in that particular circuit, which is what took out your original fuse. . .your fuse did it's job by blowing and saving the circuit. If you can get your hands on a schematic, you can trace the circuit and find the short.

How to test for bad transformer


  1. To test a transformer you need to know what type of transformer it is first. There is a step up transformer which steps the voltage up and a step down transformer which steps the voltage down.
  2. You will still test the transformers the same way for step up and step down transformers. If it is a step up transformer apply the incoming power to the transformer or plug it up. Now take your multimeter and place it on the AC volt scale and test the voltage if the voltage on the data plate says the transformer should step up to 220 volts and it doesn't then your transformer is bad.
  3. Now repeat the same steps for a step down transformer. Plug up the incoming or primary power and test voltage on the outcoming or secondary side the voltage should step down to the proper value. If you don't read any voltage on the secondary or outgoing side then the transformer is bad.
  4. To read the voltage place the two meter leads on the secondary side, or the side you will plug your equipment into. If the secondary side is an outlet then place the two meter leads into the top two slots in the plug and read voltage. You also want to make sure the incoming power is working as well. Otherwise you will be reading a bad reading every time.

Dead no power.. checked main fuse, worked fine last night, went to turn it on today and nothing. its a sx-316 not sx-315, I say this because it tells me this is not a valid model#, but sx316 is printed on...


Check the resistance of the primary on the main power transformer, (with power off) should be 1-3 ohms. If open you need a new transformer.

If good turn it on and check for ac voltage (120v) there.

The transistor of my pioneer sx-203.i remove my power transistor so that i can replace but it lost...i dont know the code of the power transistor or the main transistor.


Tell me the board no or exactly where it is located or there will be a number like T XX for denoting the sequence no of that transistor

i have a good one working now with me
if you have users manual please send for me

My sx-315 pioneer receiver overheated and shut down.


Probably the thermal fuse in the main power transformer. Check for ac on both the primary and secondary of the transformer. If you have 120v ac on the primary when the standby light is off and nothing on the secondary you need a new transformer.

I have a Pioneer SA_410 Amplifier. Has open circuit mains transformer. Could you advise what its AC secondary output voltage & current are? Regards


I have replaced many thermal fuses in power transformers. Is the primary open?? If so, cut the copper shield on the primary side of the transformer with a pair of cutters and peel back the paper insulation to reveal the thermal fuse. Replace it and everythings OK!! If the secondary is bad there's no hope, of course. Anyway, in the meantime I will research your question and post again very soon. I have several old pioneer schematics and know where to find what I need.

a little bit foolish thing: see if you have both the speaker channels (A and B) down. if you have both down it doesn't work - didn't for me.. and obviously make sure you have the right letter down - same outpout as your boxes
