Picked up another cheap 'spares only' PL-12D.
It arrived yesterday. Looked pretty good, but would not rotate. The main bearing was completely seized. I took the bearing out and could not budge the shaft, it felt as though it was 'superglued' in place. Anyway, I soaked it overnight in cellulose thinners and voila! It spins. Now perfectly free and no wear in it. Very nice. I'll give it a clean and lube and bung it back in. Everything else on the TT is working fine and in tidy nick.
