DJ is getting relays SOMEWHERE, but they may not be exact fit. As you, ROmad, know, you can modify a SPDT relay by cutting off one pin.
I have not looked to see what DJ used in mine, hate to tear into it AGAIN. And I can say the relays in the new SLK230 version I bought are electrically the same but physically different.

I guess we gotta remember, our RCMs go back almost 20 years now. Getting EXACT replacement relays may be a pipe dream now, but not all hope is lost, if the DPDT version can be adapted, we are still good.

I do have ONE relay left, it was in my box of switches and bezels for some reason. Makes me think there may be one or two more I don't realize I have.
