Marantz Model140

Hey guys,
Currently reconditioning two Marantz Model 140’s. I am look for a replacement relay possibly two. Does anyone know where I can get one. Interesting fact, I spent about two hours troubleshooting the VU meters on one of these units and turns out a wire in the back where the speaker terminals connect was in fact disconnected. Was difficult to see due to the fact that it was behind the power transformer. Anyhow I love the M140’s this is my third one so far, all of which I received for free. The goal is just to replace the broken relay and change out the other in the second amplifier. Many recommend taking the relay apart clean/sanding it, which I have done. Don’t see the point in having her open and not replacing them with newer ones. All three came from the same place and are virgins, I want to keep them running like new. Meters have been calibrated, proper biased amp structure. I send my gratitude in advance.

Thank you! They aren’t too expensive, bought four just for the future!

I know this isn't a real new post, but compared to some regarding 140 relays, it is.
Did you put the relays in?
I've been doing some digging, and found service manual updates for the 140 that are dependent on serial number.
Mine is a 1019 hundred something or another.
It's new enough to have the upgraded diodes, but old enough for a relay replacement.
