FWIW, the crate V18, V33 and V50 all share the same ill fated switching power supply. The supply seems to last longer in the v18's, possibly due to 2xEL84's drawing less current than the 4xEL84's in the V33. I haven't heard that much about the V50's, as they don't seem to have been as popular, but w/2x 6L6's their current draw would be pretty close to what 4xEL84's are pulling.
Anyway, if it works and stays working, good deal. If the power supply croaks, well, they ain't making any more and they can be a royal pain to the repair.
EDIT: oh, and yeah, if it was sitting in front of me, working, I'd definitely shell out $150 for it!
