1000w monoblocks, appx 60kg’s each ! Any ideas?

Just collected these 2 this morning.
I’m no weakling but these took all my strength to lift them .
Built by a medical doctor ( now deceased) whose hobby was electronics and his passion was hifi .
These drove 4 speakers, the fronts were about 6” tall and atc’s at the rears .
The son said they’re 1000w each and were originally designed to have triple outputs bass/mid/treble but at some point the builder of them decided to change them to a 2 output design ( just as Alzheimer’s kicked in ! ) this might explain the unconnected brown wire .
SO should I power them up ? ( and run ) what would you guys do ?
I’m no electronics person, just into my hifi .

Without a schematic you’re kind of going in blind. If you know what you’re doing you can work your way through it with a lot of time, but yeah….

If it were me I would power them up on a dim bulb tester or some type of current limiting supply and see how it goes. If they power up nicely check for offset and then put a pair of sacrificial speakers to them. That or try selling them.

I doubt I’ll use them but it would be nice to hear them at least
