Replaced 6GJ7 and 6U10. No improvement, but I did find the source of the fuzziness. This TV is incredibly picky with its input source. I have it on a splitter with the CTC-25, and it does not like it one bit. If I plug in the source directly into the VHF tuner, it's fine, but with the splitter, it has lots of squiggly interference. The RCA does not. Nuvistors anyone?

If the interference occurs when you have both sets turned on, turn off the RCA to make sure it's not radiating back into the Zenith. Probably not, but doesn't hurt to check. Also check for broken RF cables.
