Tweed Princeton
There's what looks like a tweed Princeton chassis on eBay. It is a wreck but could be the basis of a nice restoration project. I am going to pass on it as I don't have time for it. The thing is not much more than a skeleton, but there's enough there to get started. I doubt the transformer works. Clean up the chassis, re-chrome it and repopulate the circuit board, buy new transformers and you might get it to work. It is not less work than building one from scratch but the original chassis and fiber board would make it a few levels up from an ordinary DIY project. I bet that hunk of junk goes for $250-350. Anything less is actually a bargain.
I have a reoccurring dream that I find one of these in a box at a flea market and buy it for a dollar.
