WOW!! I'm surprised that TV is still working after 10 yr. This
chassis is a dog, enjoy it while it is working. I work for a shop by
the way and haven't seen a CTC170 based tv yet I do have schematics
for it.

That's unusual feature haven't heard of that.

Being RCA, and knowing the RCA CRT is, they will last much longer
than that like 3 or 5 years more based on your description of picture
quality. For this reason, I like to own either RCA or JVC, many of
them especially JVC 27" sets used RCA tubes.

LCD and Plamsa are not nice. Too many minuses and primarily cost.

I'd look at OLED developed that far and alteratively DLP which
is very *GOOD* and is here now. Old standby CRT based projector is
cheaper and bright.

By the way, CRT based projector that is HDTV compatible (16:9 format)
in 1080i mode shows very little lines. Actually, picture looks
purer. There is 16:9 format direct view CRT sets but hellcious
heavy.
