After what I did for my main system, I might suggest you consider buying a restored vintage unit, or, ’original condition’ with good clean faceplate/glass/controls, have it shipped directly to Audio Classics (or someone you know), have it restored and then sent to you. I bought a McIntosh mx110z Tube Tuner/Preamp in original condition. Got it, sounded great, ... after a year or so I figured, what the heck, I’m going that way, I’ll drop it off. The best thing they did aside from .... is replace all the rca jacks with new gold plated ones. Of course FM alignment, replace a resistor there, a needed faceplate light bulb. Point is, had I been thinking ’long’ I would have had a greater start and skipped one leg of shipping. Those old jacks are a weak point I discovered.
this one says restored, but the faceplate is badly worn, I would avoid that.
