Already got a set of spares. I could use a tester for some other projects anyway, so it wouldn’t be wasted money. I’m starting to think maybe I bit off more than I can chew, and should have started with black and white tv first. I’m learning that color has a lot more going on.

What about the other set you mentioned as having for parts. Does it work? |

Sorry for the confusion-yes, the restored set is working like brand new and has the upgraded polarized cord to avoid a hot chassis. I just like to have spares of everything, hence my search for parts. I’d like to start cutting my teeth on the donor set to learn what I’m doing.

It seems that every transformerless GE set, B/W and color was equipped that way. Also, most other US makes from the early 60's did as well. Probably easier to get U/L approval. |

Is the purpose of the polarized cord solely for safety, or are there any other reasons as well?
My set's plug was replaced at one point, and the replacement plug is non-polarized. Is there any concern/risk of damage to the set if it's operated with the polarity flipped? I wouldn't think so, but just wanted to ask. |

All kidding aside we changed all modified cords as a CYA step. They are redundant as everything is plastic. No effect on operating the TV. BTW some chassii are hot either way...... As for doing a B&W first just get your set to be as good a B&W first then worry about color. Series string sets to find open filament do this. Meter on AC, ground one lead. Go along pin 1 & 12 til you find one with no AC on one pin. BTW you will measure 120VAC all along the string. That will not match the data. Its because with the open there is no current so no voltage drop along the string. 73 Zeno LFOD ! |

BTW, those PortaColors sure are nasty to totally disassemble to replace the CRT. |

Also found damper most likely followed by a tuner tube. For the tuner part of string find the brown wire ( most sets ). Never did a jug on a PC. Only ones changed were under warranty. GE had a way of "pouring" parts into a set without a care in the world that someone would have to fix it some day. When the started building some great stuff they were soon gone......... 73 Zeno LFOD ! |

The only reason B/W sets were recommended was to get your trouble shooting skills up to speed. I have several B/W sets, but if the program is in color, I prefer to see it in color. When I first working on TV's, I never seen a color set, except in the stores and there was seldom anything on in color. The B/W pictures on the color sets didn't compare with the pictures on the B/W sets of the day. I'm surprised that they sold as many sets as they did.
