I have a Hi-Fi setup too!
I've had one since about high school, my parents had one when I was really young but I know next to nothing about it. My first stereo amp was I believe a 70s Kenwood of some kind? Very close in design to what
@sibusen posted above.

That unfortunately died, I think it was a transformer issue? Don't remember. I still have it, it's just still broken. Then I got a Pioneer Stereo also from the 70s not long after, looked VERY similar to the Kenwood.

I also still have that one, and it DOES work, kinda. It has major stereo issues, the left channel is nearly completely dead and even slightly touching Any of the switches or dials causes Massive crackling, but it DOES play things.
Right now I am using a modern day Sony STR-DH190 Stereo Amplifier which works wonders!

The turntable I've used for all my stereos is a ~1977 Technics SL-1910 Direct Drive Turntable. Very nice! No complaints.

My speakers are two passive speakers I got off Amazon long ago, I forget their brand. They work well though! I also hook up my lil portable Sony Walkman CD Player to play my CD's out of it too, using an aux cable.
I would take a photo of my setup atm but my room is far too messy to show.
