I did a little more work before installing a new 16GP4. The old candohm was replaced with an aluminum housed chassis mount power resistor. A beefy Panasonic high-ripple current 105C electrolytic main filter cap replaced the Nichicon I had tacked in earlier.
I then installed a vertical retrace suppression circuit as described in Rider TV Manufacturers' Receiver Trouble Cures - Volume 1 Next I popped open the focus rheostat and bridged a break in the resistance wire. It's working very well now It sure looks strange with that dinky 5" CRT installed. A strong, rebuilt 16GP4 will take it's place. Ah, that's better Time for some tweaks with a test pattern generator before installing back in the cabinet. |

Looking good!
Did you paint the metal cone of the CRT red, or did it come that way? Nice to have a little "reminder" on those that are not enclosed with an insulated cover. jr |

That's how I found it in the set I salvaged it from. I've been told that indicates it's a rebuild rather than being a warning.
There's a visible neck weld and has a rebuilder's label on the cone. I think it makes a great warning and they all should have been red from the factory. |

Hi Bob,
Picture looks good on that rebuilt crt. I recently finished a RCA KCS-47 set with a 16GP4 that's dimmer than your old 16GP4. Hope you hold on to the old one, you never know when you might need it. |

Yes, I have it. I hang on to all my weak CRTs. Better than nothing and maybe can be rebuilt someday. Got plenty of room with the new house.
