Oh yes, Muntz's sets were known to be rather minimal. And not likely
great performers, either. His big contribution to the industry was
measuring the screen size diagnally, instead of the annoying square
inches or H X W others did. Supposedly, though Admiral used diagnal
inches early on, too.

Hehehe. I'd love to see a Sam's of a Muntz.

RCA in the 60's started getting really cheap with their designs. One
B&W TV I saw the schematic to had 2 IF stages, then a single tube for
the video out, another for sync, and then the vertical section was a
single tube. Their color sets had single tube vert sections, too.
Triode output amp too, IIRC.
My general rule of thumb is any TV without a power transformer was
likely a cheapo set, so don't expect much...
