Nice stereo porn! I'm a big fan of the M-60/65 series. Nice work!

I noticed the M-65 has a plate bond over the bridge rectifier diodes, silver squares next to the transformer. Thought that was interesting. M-60 doesn't have that. Hmmm.
Same goes for the M-80/85. The only electrical difference is an on/off switch for the displayThank you for the praise. Basically the M 60 and M 65 are the same, only the M 65 has minor modifications.

M-60/65 makes the same amount of wpc on the bench. As does the M-80/85.

My first chernobyl repair was an M-60. I didn't know my ass from a fuse and used NTE parts to fix the blown channel, lol. It made music. I took it to a local stereo shop anyway to QA the thing and they said all was good at rated power.
I love the front end design on these. Good stuff.

Did you add this plate on the rectifiers?

Interesting, mine doesn't have that plate.Hi, no, they weren't added later—it's original.

4 of mine didn't have it either. Maybe it's a crumpet warmer for the folks in the UK.
my m65 doesn't and i'm in the usa4 of mine didn't have it either. Maybe it's a crumpet warmer for the folks in the UK.
I have some FOMO about this. I stared at my SM looking for UK variance & stuff. 
I'll bet it's more of a anti-vibration in class A mode thing than a heat dissipation deal.
