Replacement protection relay CR-1020

[mgl99]

Does anyone know the correct part number (either Mouser or Digikey) for a replacement protection relay for my CR-1020 receiver? Info appreciated.
Thanks,

M. Lang

Thank you for the info on the protection relay. Problem I have now is that I am going to rebuild the power supply board. The service manual parts list for the boards seems quite cryptic to me. I need a list of caps for the board so that I can order what I don't have in advance. Does anyone have a list of caps for this board?

You have the caps in front of you.Inventory whats actually installed.Don't rely on the SM parts list. Lots of errors..

I always mark up a PCB diagram and/or schematic with what is presently on the board, including the correct polarity as the docs and/or boards are sometimes wrong.

Bounce that against the schematic for any special caps.

Thanks, but I believe this board and others in this receiver have been worked on before. If I suspect that someone has been into it before, I like to have the manf. parts list to check against. The schematics are typical of those included in a service manual. Extremely small and nearly impossible to read. I have already inventoried the caps installed on the board and made a list. I like to gather as much reference material as I can before I start pulling components from the board. In addition, sometimes the polarity markings on the PCB have been wrong. Since this board is obviously not working correctly and cycling the protection relay erratically, at this point I don't know if it may be the result of previously poorly performed work. Some of you out there may be shaking your heads and laughing at me for my methods, but I have found over time that my methods prevent inadvertent errors on my part and they have worked for me.

Certainly if you think it's been dicked with before, it's best to verify. I get that.

While I have compiled for others, I unfortunately don't have a complete list (xls) for the CR-1020/2020 handy.
