Need Tuner Dial Light Bulb
Does anyone know where I can get a tuner dial light bulb - it is for my ctc-44A chassis RCA trans vista color tv from 1970. I can't find anyone anywhere - I substituted the UHF bulb for the VHF for now (just blew out), but would like all operational. Any leads would be appreciated. No schematic is to be found anywhere, and i don't have the model number either - the tag is long gone unfortunately. Again, thanks to all of you who helped me get it up and going again! Joe

Is there a number on the base of the bulb? If so, you might could get one from Radio Shack or Antique Electronic Supply (www.tubesandmore.com).

It's not one of the bi-pin lamps, it it? RCA used some of these - if it is a bi-pin lamp, I've got some. There are two types - both have a black metal cylinder around the bulb - one type has the cylinder open at the end, the other with a closed end and a rectangular window in the side.
Cheers,

Get the number off the original lamp and we'll see if we can help you, I have many bayonet base lamps if that's what it takes, Dave.

The 47 is still a common lamp. I think even (the formerly beloved, now hated) Radio Shack has them, maybe in the catalogue if not in the stores.

Your set uses a #219 bulb. RCA p/n 117435. Its a 6.3v 250 mA bayonet base with a spherical envelope. Very important to use the correct bulb, especially in an RCA. The #47 will be too close to the dial drum and will create a burn mark on the channel strip.
You should replace the other bulb too. Im surprised it worked when you swapped it out. Every time I pull a tuner with its original working dial lamps and then reinstall, 9 times out of 10 the VHF bulb won't light! Here's a place online who has them in stock: http://www.electra-ica.com/special/microlamp/
