On the 14" Philco I just did I accidentally caused a short and fried my fuse resistor.

I replaced it with a pigtail fuse and a Thermistor, the same type used in the Predictas. I didn't do anything fancy like a terminal strip (I was tired of fooling with it), just joined them together and positioned it away from any possible contact with anything else. I used on original base so it just plugs in the original socket if I find a correct one.

I figure the hot resistance is probably fairly close to the 4.7 ohms and it'll give the set a softer start.

The fusistors have exploded in several of the Predictas I'll be working on soon so I'll have to rig up a replacement like you did.

I struck out on finding any knobs. Oh well, I'll just go with what I have.

I've moved on to cleaning up the cabinet and safety screen. One corner is damaged but I was able to flip it 180 and it's not as visible.


Here it is after a whole lot of polishing. I used Kat Scratch Out and Meguire's Cleaner Wax on the cabinet.

Dam, now there's two of us looking for a screen!

Arg! I thought I was done, but there's something shorting out around the vertical height control. I'll have to pull the chassis back out and investigate.

I found a solder glob wedged in the vertical size/linearity control! I cleared it out and put the set together yet again.
This time it played fine and just in time to catch one of my favorite Outer Limits episodes - Demon with a Glass Hand

dont you just love that ! why cant those problems like that show themselves while its apart ,or on test run's, nope its got wait after the screw been put in and its all wiped of and you think you have won.

What a superb end result Bob! Great looking set with a great picture to boot! Cheers Glen

[bandersen]

Thanks! One last bit of business was to replace the power cord. Luckily, I found a NOS cord that fit perfectly.
You can see where there used to be an antenna but it's long gone. I've been using a 75-300 ohm balun for my testing.

ill definatley be saying a prayer over it when i hand it over to the postal service.

[snelson903]

the moto i showed pictures of here on bandersen thread awhile back has made it to the west cost undamage via the u.s postal service , and is now safe in the hands of the boobtubeman. i guess you can trust the postal service as long as you intomb it in a cocoone ,so they can still use it as a football. lol

"resistance is futile"....You will become a member of the smashed packages club one day....Lord knows I am.

Allready did... when i had a 1937 radio sent from LA.. A short trip up to me, but the speaker came loose and bounced ALLLOVER the inside of the radio. Took out a couple tubes, and the field coil speaker was shredded..

The way the motos are set up, i was anticipating a tube jumping ship and goin for a tumble, Much to my suprise, it held together on the LONG trip..

I almost believe they see the insurance sticker and it keeps em humble when they handle it, Also gotta give kudos to Snelson for creating an internal fortress of a box for the long trip... Took me 15 mins and a knife to access the inside of the box LOL!

But its here, and it looks and runs like the previous pics shown, Futuristicly, it faces a teardown, painjob, and full recap, rebuild....

My first tv model is home

Mission accomplished and thanks to all

I always wondered if buying there insurance doesnt help make sure better handling of a package ,its kinda like paying protection money to the mob. lol glad to here it took 15 min to break into the box ,tells me i did my job right .you can probley make a dog or cat bed out of the extra blanket and stuff i put in the box. lol

[Boobtubeman]

Kitty was laying on them 10 mins after they exited the box LOL!!
