Frankly, older SS gear is not the same audio quality as newer gear. Example is the Rega Elex R. Vintage tube gear needs higher quality coupling capacitors such as Russian K40Y-9 at sound as good as most new tube amps.
The new tube amp manufactures have known for a long time the coupling capacitors make a huge difference. Better solid-state amps have upgraded from electrolytic coupling capacitors to polypropylene capacitors. Vintage SS did not use polypropylene coupling capacitors.

I don't remember what electronics my friend had. So I don't understand your reply.

he gives no distinction to 'Older Tube Gear' as in what kind of time line.
Back around WW2 it was experiments on the circuits. That was primary. The components became important to different manufacturers who were discerning as time proceeded throughout the 50's. It continued to progress as time went on.
There was a lot of things happening along the way in the design of EVERYTHING and it happened pretty fast because of competition. Those guys meant business
BTW, I had the russian teflons and a multitude of caps 20 years ago, I compared them with several brands and they were nothing special at all. I sent a letter to Stereophile which was printed saying they sounded 'bleached' as a descriptive. I compared them to the best I had at the time, the VH Audio teflons.
They might have been a good match for a system that sounded quite 'dark'.
