Alot of the older HiFi stuff was built like a rock. I still troll the pawns shops, etc. looking for older Marantz, that kind of stuff...
I almost bought a Marantz. It came came down to blue or green lights, and I went went with green. You’re right about the old gear being built like a rock. That’s another reason it’s so cool. I love the feel of my Yamaha’s weighted tuning knob, as corny as that sounds.
