Later known as Amoco Corporation.

First thing to do is replace all electrolytics, wax paper capacitors, old paper oil capacitors. Those types always go bad through high ESR, high leakage, failing open, short ect. Tubes seldom are an issue. Most likely tubes that would fail are horizontal output tube and High voltage rect., or damper tube.

That is so cool! And what a coincidence... that is what happened later to this tv. possibly, it recently stopped wanting to power on at all. Thermistor looks like it fell off board, disc fell off leads very odd.

mine had the same problem. luckily there was a Heathkit Center near me.There were a couple of zeners in the SCR Horizontal output that were kinda like the old damper tube in vacuum tube sets. Sometimes the particular zener had a prob with the flyback pulses and would run hot n overheat. I replaced them with 5w units and bent a piece of .035in.thick by .25wide aluminum stock around the body and left an inch and a half tail to act as a heat radiator and cut a hole in the Masonite back for a muffin fan. Kept it for about 14yrs and gave it away as the 25AVP22A was losing the red gun.

@@Mr39036ce first time around I took the unit to a repair center in Philly, they eventually sent a more robust high voltage assembly and that worked trouble free.

@staberdearth3130 they did offer to repair but at a cost. I had found the shorted diodes and decided since it worked successfully first fire up I would try. The replacements were fine and the set worked great but the diodes ran exceptionally hot. thats when the home repairs were applied. And the upgraded HV assembly was never suggested,at least to me. It was a pre assembled sub unit in my GR-2001.

@@Mr39036ce possible that I got an earlier version? My first fried high voltages section was within a week of assembly.

Sadly I do not have any vintage tv studio cameras. I would love to have one or a few obviously. What few I have seen online are quite pricey but not a surprise since they are super rare.

@@SuperZed21 Not sure how the cable tv business rolled out in the good old USA (I'm Canadian) before the great monopolies had their way, but if your area had some local cable tv companies they may have hosted community access channels (showing town parades, county, town and school council meetings and the like) those often at the time had the best of tv production equipment (since they were pretty profitable early on) some of that may still be stored in a successor companies dusty storage nooks, another possibility is large high schools and local colleges/technical institutes many were loath to sell off such goods having some weak hope it might come in handy some rainy day or feared landfilling electronic goods that might leach poisons into the water table and so even yet those goodies slowly accumulate dust year by year.

Walter Cronkite was an excellent speaker and good at delivering news. I see what you are getting at. Are we all living inside a giant computer? Maybe, impossible to currently prove. Certainly is plausible. No point in worrying about it though. My fields of interest include vintage vacuum tube tvs, vintage computers, computer building, vintage consoles, and AI.

Yep this tv was having issues with high voltage arcing. we are talking voltages in excess of 30,000 volts and possible x-ray emissions as a result of this coming out of the high voltage rect. tube.

@@SuperZed21 Sheeeéêēèëeeesh! 😳😬

I am too young to remember projectors for movies. I am born in 1994 and mostly remembered VHS tapes running in VCRs. Also a few rare times a laserdisc and laserdisc player! And later DVDs. All now obsolete formats.

This tv was fairly advanced for the time, having two IC chips!

The CPU is an AMDK6-2 running at 333MHz clock speed. Local bus clock speed only up to 66MHz. Hopefully that answers your question. I have a digital copy of the manual for this laptop.

Oh man I was one of the OG's. I still remember back in 3000 bc when I saw the pharaoh kill my parents to make the millennium items. Good times I tell ya.

Interesting :D
