I always thought that "Phil Katchaturian" song, "Lois Lane Blues" COULD have been a hit, had Toby released it...

Nope, no tubes in this Chromacolor; it's the sets with screens smaller than 25" that are hybrids.

Wrong. Zenith did make 25" screen hybrid sets (I know your set is solid state). I have a Sam's folder that shows that my hybrid chassis was used in both 23" and 25" sets.

Yup, got to replace those caps for sure just to be safe. At least that's one thing I don't need specialized equipment for. What exactly would I replace them with, and how much voltage is running through them? Should I just short them to drain the charge?

Yup, I certainly don't want to burn up this set. The replacement caps will have to wait for now as I'm pretty broke from moving expenses, and I would like to find a local source for leaded solder. Of course I'll avoid running the set until the caps are replaced. In the meantime though, it would be nice to know the substitute cap number. BTW, are these caps polarized? I don't want to swap ends and blow it up even with the right caps.

Alright, I received the OEM safety caps recently, bought out the last of Talon Electronics' stock. They had just enough. Does it matter which way these go in?

If they have a stripe match it but the are not polarized.
Will work anyways...... 73 Zeno |

At long last I got some Kester and installed the new safety caps. There's only one under the chassis. I also cleaned the crud off the back of the CRT and the 2nd anode cap and cleaned the volume control and now the set works fairly well. I hooked up a pattern generator and finally got vertical size and linearity adjusted properly. There is one issue: the whole picture is shifted slightly to the right. I can't find a horizontal centering control.
The picture doesn't do the set justice. Edit: Got rid of the Garfield DVDs and re-took the picture when playing an episode of Corner Gas. I had to have a more adult version of infantile. Great, the first pic was sideways and this is worse. What gives? Last edited by Jon A.; 09-19-2016 at 11:17 PM. |

For shift look at the 9-57 board for a 330 ohm.
Change it to a 1 watt film if it hasnt been. Upright chassii with the 9-90 board have the same issue. Recheck that you changed ALL the 22-5001 caps. I am sure these had 5. Check for a 1.5 ohm at the HOT base, they drift. Be sure the hoz hold is centered. Pix should snap right in on channel change & not show lines. If its at the end pull back on the sleeve & move it past the stop. I dont remember either size or centering on these. And last it could be what you are feeding it. 73 Zeno |

I see only one film cap on that board; is that the one I'm looking for? (see pic). Also, is there any way to add a direct video input to this thing? The picture I get through that cheap Radio Shack RF modulator is rather disappointing.

( 330) to r-r-org ( 22K). I remember where it was on a 9-90 but not a 9-57. You can put video in just after the detector. It usually works good but sometimes not. Audio I would have to see the schematic. Try using a VCR as a modulator first. 73 Zeno |

Very, very nice Zenith. My 1973 Zenith set uses the 25DC56 chassis, only it is not Space Command.
