Tim,
As to your CT-100 dilema, I'd go with the advise of others here. Get the cabinet repaired/restored. It will add to the value of the piece not the opposite IMO.
I thought I heard a much higher figure for purchase of the Marilyn Monroe set, more like high $30's. Hey, you think someone who paid $37K for a portable tube B&W TV might pay half that to get it working?
