Need Tuner Dial Light Bulb

[joeseattle70]

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
