What I was trying to say,& that obviously has gotten taken about as far out of context as possible is that these Porthole style sets were and are STRANGE looking-Especially now,as it seems that the normative "Look" for a TV is a black/grey rectangular plastic box w/little or no adornment at all. When Portholes were new, having a TV was still something of a big Deal, Zenith kinda run 'em up the flagpole,as the Sets with the "Giant CIRCLE screen", My Porthole is a12" tabletop model that is vinyl/leather covered. When I show it off, most people that are roughly my age-60 say they can remember them, but younger folks & kids are completely befuddled by it. Its also amazing as to how many people claim to never having seen A b/w TV of any sort...

Zenith had a reputation of making strange looking radios too. Almost as if they were expecting future generations to collect them. ;)

OK, here goes. I've started on the restoration of this TV. In the next few days or week I'll get caught up with the progress that I've made.
Fist off I'm working on the HV cage and Fly back. The FB coating was pretty melted and cracked. What I did to restore the FB will be part of the upcoming posts. What I'd like to show you guys and get opinions on is that the 1B3GT filament winding that is around the core of the FB might have an issue. The wire is held off the FB core with 2 thin pieces of a fiberglass like material. Where the filament winding has passed through those pieces, it looks like they "dug" into the insulation, thus compromising the insulation. Here are 2 pictures of the filament winding and how it is held in place around the FB: https://tvrestorerguy.com/wp-content.../100_7897a.jpg https://tvrestorerguy.com/wp-content.../100_7896a.jpg Now here is a close up of the damage to the insulation. It goes in some but not all the way to the conductor: https://tvrestorerguy.com/wp-content.../100_7920a.jpg I think I need to replace that wire. Now here is another question. If the original wire is lets say 20Kv and I use 40Kv wire, will there be enough "juice" to get through the "extra" insulation of the 30Kv wire to work the 1B3GT? |

Sure, this is just a transformer with a one turn coil providing the 1.25 Volts for the 1B3 filament. Turns ratio is the only thing that counts here, extra insulation on the wire will not make any difference. jr |

Uhh, now you've got sumpin even I never heard of...(Grin) STILL wish I could "Big Deal" a bunch of youse guys to come pay me a visit sometime next spring.. I'd take you to Sneedville,where they have this WILD commemorative to their War Dead.... Its a statue of a reputed Italian soldier... Seriously. They wanted to put up a statue to their War Dead, but they couldn't afford a NEW American one, so they bought a USED Italiano one..Hawk nose, handlebar 'Stache" holding a Carcano rifle, & a WTF-Am-I-doin'-HERE look on his face.. Most of you know that I'm a reasonably good Bullchip Artiste,but even I couldn't dream up anything to beat that..

Guys, Lets stay on topic. thanks.
|
I'm TRULY sorry that something I said got a bunch of y'all all upset & Discombobulated...THAT, of course, was/is never my intention.
