This sounds like some sort of trick question. Maybe better to post at an EE forum.
Amp design is one thing but quality of components is just as important, which we can't tell from these photos. And ultimately it boils down to what you're trying to achieve.
One of my favorite classic amps, possibly the best sound I've ever had from a 50x2. super simple layout. Anyone recognize it?

Couldn't tell you the model... Perhaps a ClassA 100? It's quite a bit larger than my old ClassA 50's, but looks VERY similar. Soundstream... the OLD SCHOOL stuff, when Soundstream MEANT something!
The old Soundstream sounded so good, because of the minimalist approaches always used. Note how FEW components are in the signal path, between the inout and the gain stage... That minimalist stuff has all gone away, today...
It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Damn, good eye! Class A 100ii. Currently collecting dust in the basement with some other relics.

As long as I'm avoiding work let's try another, see if you get it.

(the heatsink shape & molex should be a big hint)

As soon as I did I'd want it back. Even if it's just to occasionally hold it & pet it lovingly.
I don't know. If you're building an entire O/S SS system complete with tape deck or something let me know. I could probably be talked into it.

Linear power? Possibly a 2502?
