Try getting some play dough--let it dry & harden-- and send molds to all people w/possible parts, also any knob makers who may want to give it a whirl. That way you don't have to send original part & worry about losing it.

A patch job may prove difficult to gear, I have done this to vintage toys w/little success, usually gear breaks again where glued from stress. A good amount of torque is probaly needed for large old type tuner to "clunk" into place. Adding metal reinforcements on both sides as patch would work if tolerances for entire assemly allow for extra room. What about Thin washers same diameter as gear, drilled w/ holes (to fasten both washers and gear together) at three corners in triangler pattern??

Yes there is plenty of clearance on both sides of the gear, and checked the mech again and almost sure that I can swap this gear into either the tint or the intensity mechanisms, which have almost no stress at all, practically zero, very free-spinning. JBWeld and couple of washers should do it, maybe put 3 little bolts thru the whole thing after it hardens. Hell will probably be stronger than it was originally! Fortunately it was a clean break and no teeth were lost.
Now back to seeing what I can get out of the set picture-wise and finding out condition of the pic tube. Tube in the tuner is reading a leakage on my tester but other that the tubes check out ok...Frenchy

Hey is just pulling the 3/4 amp fuse a good enough way to start testing the tv i.e. warming up tubes and caps, sound, tuner etc.? This disables the HV and vertical and horiz. to the pic tube, right? thanks

Did you find a battery yet? What shape is it? I used an older style 4.5 volt flash battery to replace a mercury battery in a radio a few years back. Worked great, and still works today. Maybe that will help.

Battery is about 2/3 length of an AA, and maybe 25% fatter. Who still sells old flash batteries like this 4.5 volt one you mentioned?
Powered the set up without the fuse tonight, get good sound though the tuner needs cleaning BAD. No caps getting warm or anything else funny so far.
Still may need to get a new 6ea8 for the tuner as it reads leakage on my tester but not sure yet...Frenchy

Hey Houston, we have a picture! Not to shabby, this is without the booster on it. Comes up at normal speed after turn on. Brightness control needs to be cleaned, really glitchy when you flick it around and full-on varies in brightness depending on the flicking, which may be part of the problem. But turned up pretty high it's a good pic and I haven't cleaned any controls yet except the tuner, and this is with a crap antenna. And haven't messed with any gun settings or anything, this was just a 'what do I have here?" test.
Not getting any color, but at least good b&w, guns seem balanced (looks bluish in pic but it isn't). Get a little purple on some of the shading at extremes of the fine tuning, other than that, zero color no matter the settings, but again, crap antenna, need to hook a vcr up to it now. What does b&w with purple shading sound like? Maybe the color controls are dirty as hell too.
Here's a pic of what I got so far...time to pull it out again and start cleaning pots...Frenchy

French,

Look about halfway down this thread...

and you'll see the Hoffman Solar Radio that I used the flash battery in. I had wrapped tape around it so it would fit better. IIRC, I found the battery at Walmart or Walgreens. That was a couple of years ago. I'm not home right now, so can't really get the radio to tell you the number on the battery. It sounds like this battery would damn near fit perfectly in your remote.
