No channels below 16? Wow.
I'm not really that familiar with Philco sets, but I will say this...
A lot of TV restorers like to dive into projects by recapping everything in sight. While I do understand the need to replace the caps (eventually) I've yet to meet the "reasonable" condition B&W set that couldn't produce a picture with original caps. Recapping without any poking around seems a bit scatter-gun to me.
You most likely have some weak IF tubes, or a tuner RF amp that is completely shot. No harm in running the set, on any channel without a VCR, and tapping some of the tubes in the tuner/IF section with the end of a pencil or something. If you get any kind of snow/static, you're getting closer to the problem area. Rocking the tuner knob wouldn't hurt either. (Dirty contacts)
The next step would be some tube substitution in these areas (if you've got some extras). If your set is like most Zeniths, and uses a few of the same IF tubes, try switching them and see if it has an effect. If yes, you've got a bad tube.
