Although this set probably does have a MOV, most likely that isn't the problem. Lots of even older TVs have a capacitor across the line, for RF filtering, and I have seen one of them blow once while unattended. Went off like a fire cracker. Funny thing was that the TV was still playing just fine. If I remember right it was one of those ceramic encapsulated paper capacitors, and rolls of foil was all over the underside of the chassis. PS, it was a Sears (Warwick) made all tube type set. Many of the old radios back in the 30's and beyond didn't even put a fuse or anything in them. If something shorted, Bye, bye power transformer. Bring it over, I'll check it out.

Anything tube that don't have instant on, and has had it's line RF filter cap changed I trust more than anything you can buy new since the power switch actually disconnects everything from the line (versus SMPS that are always drawing power and feeding power through parts less reliable than a switch).
