New member - interest in restoration/modification of older console stereo

Howdy all,

I got an older console stereo system at a auction on a low bid. Its a smaller one. Has a turntable and a tuner. Would be nice to do some upgrades or perhaps just repairs.

Since this was basically free figured its a good place to learn, My electronics background is college level physics (just 100 level) and a little car audio, little RPi/Arduino. So when I look at the schematics on say the DIY chinese tube amp kits discussed here I recognise quite a bit of it.

Is there a good place to start to read about tube amplifiers and these old home stereo systems? I would like to be more up to speed than I am. Going to dig into the console next week see what is and isn't working. go from there! in the meantime need to update my circutry knowledge base.
