Heart of the System:
Vintage Tube Tuner Preamp McIntosh mx-110z.
No matter what budget, what system, if mine was stolen, I would order a replacement immediately, send it to Audio Classics, have them get it back to specs (not upgrade), and have them replace all the old rca jacks with new gold plated ones like they did to mine. I'm a fan of original lighting, not new LED.
McIntosh Mode Switch gives versatility, Mono Mode, other functions I particularly need it for balancing my speakers that have L=Pads for mid horn and tweeter horn.
here's one, all the text is in good shape front and rear.
Wait for a great unit, no need to settle in your budget.
I would have seller pull it out of the case to see condition of parts and deck, to confirm not kept in damp location.
This is what convinced me to try it:

Most people have never heard a wonderful FM tuner. This one needs a strong signal, I have a dedicated antenna in the attic right above it, aimed at WBGO Jazz station. Everything they say about it is true, Richard Modaffari said there is NOTHING he could do to improve it.

MM Phone stage (2) sounds great, I use a SUT for MC into it. Tape LOOP, ....
I solved remote control volume with a more modern integrated amp.
