New GE Locomotive Project
Howdy tv dudes. Between my classic car stuff and antique telephone projects been away and off the oscilliscope screen a while. But like the clap or uncouth relatives, I'm back.
So I have a peach GE Locomotive on the bench awaiting anesthesia and routine surgery. It is totally complete with the double D CRT mask (my preference for locomotives). I last did a Locomotive back around 1997 so it's been awhile and I'm rusty on this chassis model. What particular areas should I give more than usual attention to in this project? Or is just a routine recap and component evaluation all that's really required? This one is really nice like NEVER neglected and I want it to play as nice as it looks! George |

Cramped chassis with caps hidden topside and in HV cage. Fairly standard recap unless globar heater string resistors are open then you want to make up a replacement (preferably with inrush limiting).
I did one back in spring. A recap and basic adjustments were all it needed, and it performs well for it's vintage.

Old thread here, this is a very popular set that is a decent, reliable player, and an interesting design... fun set!
http://www.videokarma.org/showthread.php?t=269086 Word to the wise... radiotronman is quite correct about protecting the speaker... it is very easy to poke a finger through it while working on the chassis. jr |

I didn't repair it, as the top of the cabinet was all bashed in and the parts were missing. The CRT was replaced in the 50's, with an RCA non-aluminized replacement and it was weak. Some of the tubes were replaced, that proved the the set was used into the late 60's. |

I have one sitting on my bench (aka kitchen counter) that I've been working on, kind of lost interest for a bit but been getting back to it recently.
It is a bit of a pain to work on, those sideways mounted boards with the caps that wrap around the backside are a bummer but not impossible. The set responded easily to recapping and is working great now. |

Thanks guys. Hopefully I'll get it into my bench later today. Wondering if I should replace the selenium rectifiers with 1N-04 or 06? Probably be smart and just go with 06.

As "Fraggle" as these things are, one wonders how they handled 'em back in the day...I betcha a "Repurposed" one w/ a Porta-Potty cabinet would be The Berries for an old TV nut...

I think it would be cooler to do it the other way around: take a rectangular screen locomotive with a good cabinet, but a dud CRT and fly, and a working portacolor with a crappy cabinet, then make a color locomotive.
