Have they ever been serviced? If not they will be in desperate need of a recap, which may sort everything out. I recapped some M3's for a friend last year. Unscrew the plate amps from the cabinet, disconnect the umbilical. Pretty easy to do if you can wield a soldering iron.

I'll take a look inside. That daughter board has removable 8 pin a ma bobs, I pulled them in and out a few times.
Another issue they make a bit of noise when turning on and off.

I am far far from expert but the caps look ok and also probably modern?
The burnt bit is the daughter board, I don't know its function but it obviously gets hot. Everything works it has that slightly toasty smell of my grandads old radio tinkering shed from when I was a kid.
Hey now from London Gammer's If You Wait has audible distortion at around the 3.20 mark, for instance, and other tracks as well which I will mention when I hear them.
worth noting I guess that I am right on these things
Which I would imagine was not their intended purpose!

Wot, no electrons?
Mr Tech Guy repaired & recapped my M20s last year. Russel is a top chap, ex-Meridian service engineer.
Note: if you deliver your units by car, the road (which is otherwise flat) has a couple of very, very nasty bumps. Watch out for the 20mph speed limit - and do that section at 10 - or you will “ground” bits of the underside

Out of interest what is the white stuff and why is it a concern? Could I just clean it off or does it hint of something more progressive?
Looks like salt corrosion. Do you live near the Sea? It's not good, all needs cleaning with isopropyl alcohol and an old sonicare toothbrush head.
Also looks like those opamps run hot, perhaps try swapping them across and see if the noise moves with them? What are the date stamps on the big blue caps? There should be a week number and a year somewhere
