Found the problem! The wall wart from my AM transmitter was right behind the tuner, and it was causing interference. Unlugged it, perfect picture on both sets.

The Digital Stream DTV converters have the AC cord passed through a ferrite bead or sleeve to minimize the SMD noise.

I was replaced the channel indicator drum on the same set
You know the tuner knob is wrong on yours.
The one i serviced had a warped channel drum keeping tuner from turning. I got one from zenith. So, i always wondered if it was a bad design or more likely a well intended tech put wrong bulb that was too hot? |

Just checked the HV on this TV, and I could not believe it when my meter read 36 KV. Adjusted the HV as low as it would go, and got it down to 29 KV. Probably one one those durned varistors.

I had a 1967 Zenith lose HV regulation. The arcing broke the CRT neck off its 25GP22.

I'd check the tube and all components in the HV reg circuit....I thought the varistor problem normally resulted in low HV, if it is going opposite of normal then you likely have other problems to address.

Maybe I'll check the HV tubes when I get home. It wouldn't surprise me if they're bad.

You had to use a GE or Zenith branded 6CJ3. There was a lot of Raytheon Japanese tubes designated 6CJ3/6DW4, that had a different heater current and wouldn't work in series with the 6HV5. IIRC, the heater in the 6HV5 was receiving reduced heater voltage and wouldn't regulate properly. |
