Guess I got too caught up in the print to really read the rest of the posts. My fetish, sorry. Just love to discover some of the clever things others design through the prints, lol. Hope you use the power. I've noted how my amp and speakers change personalities through the various wattage stages. Love them best around 2 continuous with 40 peaks, but there are some cases where 20 cont and 400 peaks can drive me to dancing. As for the relays, I will be watching also. Have had to rewind or add resistors to get what I needed in the past.
Is there anyone out here who would fully service my Yamaha M-2 amp?
So, Brutal, what happened to your search for the relay ? Back to 2005 I bought a
M-2 with R channel gone. I replaced just about all transistors and fuse resistors and diodes and it worked all right till recently. The left channel would work for ten to twenty minutes and became weak and then shut off by itself. I've re-adjusted idle current,dc balance and all that but the problem continues. So it seemed something is wrong on the speaker relay. I am glad that I've found this forum but wonder what happened to your search for a replacement to that relay.
I would hate to see the M-2 go for it's a solid build and decent sounding amp. Don't see these from Yamaha any more.I might proceed to clean up the contacts in the relay but a longer term solution should be a replacement for that unit. Any help from members of this forum would be very much appreciated.
Finder 55.12 series should fit. You just need to clip off the two unused pins.

I replaced all relays in my A-1, M-4 and M-2 with this type.
So these relays will work in the M4 without any modifications??
I have 2 M4s here and one needs new relays while the other doesn't but might as well go ahead and change them.
Thats the way it works...:yes:
A little cheaper and with 10A contacts..

verify the pin spacing....
