Philco roundie - burning smell

Kam, I'd be inclined to agree with the person who said the burning smell in the HV cage near the flyback might be simply accumulated dust and dirt--this is common in TVs that are left sitting in basements, garages, etc. for extended periods of time. If the picture looks good, just dim, I wouldn't be concerned about the flyback. Since you say there is no smoke, just the smell, I'd suspect dust/dirt in the cage first. Clean it out thoroughly, then try it again. If you still smell something hot in there, then and only then should the flyback be suspected of being defective. Again, however, if you are getting a raster, the flyback is probably good. If the fly were shorted, it would kill the HV dead away (the HV fuse in the cage would blow immediately as well).

As to the dim picture, that could be caused by a weak horizontal oscillator or output tube, low drive on the grid of the latter, or even a weak CRT. If the set has a number of years on it (since it's a roundie it probably dates back to the early '60s), the CRT could well be on its last legs--especially if the set's former owner used it many hours a day.

Good luck. That Philco looks like a great set; it should work very well once it is cleaned up and restored. The original Philco Corporation made some excellent b&w and color TVs, both television alone and those fabulous 3-way theatre consoles. I had a 19" Philco portable from 1961, trash day find in my hometown over 30 years ago, that worked great as long as I had it, and I have known several people who owned Philcos in the '60s and had very good luck with them.

Kind regards,
