Need help finding replacent relay for pioneer sa-710

[mazinkaiser]

Hi guys i been trying to find a replacement relay for a pioneer sa-710 blue line fluoroscan integrated amplifier (1980) and i have not been successful finding a replacement i tried omron part numbers:

MY2-02-DC24

MY4-02-DC24

As was mentioned in other forums and they are not the correct ones i have attached two pictures of the relay in question one from the top side and one solder side. The original is a fujitsu relay.

Thanks for all the help and the reason i want to replace it is because its randomly turning on and off even if im not playing anything if i tap the case of the relay i can get it to turn on or off so i definitely suspect the relay

MY4.. You need to snip off the unused NC pins from the new relay.

Avionic is right (as usual) about which relay. I'll add to that there may be cracked or dry solder joints causing the issue. Some of those in the photo look somewhat questionable. I would reflow all of them in that area and see if that helps. Remove the old solder and use fresh solder. But I would also replace the Fujitsu relay anyways simply because the Omron is a better relay.

Some relays were made that way back in the day. Good job!

Thanks avionic your expertise is greatly appreciated is there any way or a guide on how to determine what omron relay works for what? For future reference

You can probably, using the AK search, find the answer. I think Glenn " EchoWar" had a thread that is similar to what your requesting.
