Please feel free to ask for almost "anything", and I will look in to it ASAP.

Curious.. I too have 70's stuff stored, mostly.
Was is it better than (decent :-) current examples? Not so sure.
Example: Fender guitar amps are Highly Prized.
For their look/status but overwhelmingly for their sound: fuzzy and distorted on a player's demand.
Recently rebuilt My Fender Bassman. Discovered that many if not all the old Carbon Composite resistors had drifted in value. Some to more than double ! their values, a few drifted less But all were wayyy off spec..
Result of my reintroducing the oem part values changed the sound... Dramatically. Tight, clean sounds now dominate, the warm fuzzy brownouts are largely Gone.
Presumably rendering My fender resale as worthless :-)
Initially /briefly I gave thought to reinserting the old parts.
No I didn't, electing to go with the Factory new sound.. which once acclimatized to, I prefer.
Clearly over time the produced sounds had drifted far from what the things produced when they left Leo Fender's factory. Quite a difference actually.
BUT it's that distorted aged/sound that most identify with the brand genre.
So are these old Audio components doing similar? Likely so.

Ps: I don't admire Adcoms, they were designed and built as cheap gizmos, often sans such effete niceties as power regulation

70s amplifiers were already not using unstable carbon composition resistors and failing electrolytics usually give wooly bass, which does not sound good

Default Why?

Maybe that is the answer - simple artwork amps

@ magui1 The Sansui AU-111 That you have pictured was first issued in 1965 and discontinued in 1971 . It was reissued in 1999 and it's last issue was the AU-111G.
From the "Best of Sansui".

I would not call Sansui amp artwork. May be it is an art for somebody who knows nothing about heat radiation, convection, and inductive coupling, though....
