Replacement Relay for Guardian Electric A410-365390-101

Can anyone help me find a replace relay for a Guardian Electric A410-365390-101? It's a 10 A RES 120AC, 1345 Series, Coil 6 V DC. This relay is out of a crossover for a B&W 802 Matrix Series 2? I have found several by Panasonic or Omron, but the contact configuration is not the same.
I wanted to just remove the whole APOC from the crossovers, but I cannot find any solid information on which diodes to remove and how to bypass the relays. This would be my choice if I could find the information on the 802 Matrix Series 2 modification.
I have attached a photo of the current relay and any help would be appreciated.

I’m assuming you’ve checked Mouser? Do you have a picture of the crossover you could post?
In general, crossovers consist of caps, inductors and resistors. I would think bypassing any front end electronics could be fairly simple by jumping past them.

I have attached the crossover schematics and have marked the diodes that I will lift one leg on, and I have marked the relay points the I believe are the jumper points. I also plan on replacing the Bennic caps, possible resistors and inductors.

It looks to me like you could take out the whole block surrounding the relays and the the last diode before the output to speakers. It looks like one of the transistors for each relay is driving the relay, while the other is is functioning as comparator, measuring the input voltage against the output voltage.
If it were me I’d probably get rid of all the up front circuitry and jump it out where you see the takeoff go into the crossover.

Thanks LinderK, I will take a look at the circuit again.
 
Sorry for bringing alive the old thread. I am wondering whether you have found the replacement relay. I have the same problem with my B&W DM-2000. The delay (same model as yours, no surprise) had gone bad. I did take it apart and de-oxide the contacts and it seemed fixed the issue. But I am not sure whether it is going to last. Obviously, I could have bypass the whole protection circuit. But I really want to keep it original. Anyway, please let me know if you find a replacement. I know it could be a long shot.
 
thank you
I could use relays for a spare DM2000 set
