Yeah, a typo. I'll correct it. It should be 39.3C.

So I'm still not understanding why you said:
"the can and sleeve actually acts as a barrier to the surrounding heat of the chassis as shown by about a 3 to 5 degree difference between the can being on or off." Looks like in each case they ran cooler without the can, but not by a long shot? |

Gotcha. Thank you for posting the data, it's very interesting. Like you said there's quite a margin considering their rated life expectancy. It would be interesting to see how much warmer they run once the chassis is back in the cabinet, although a bit more difficult to aim the heat seeking light beam. What we need is a bunch of those remote temp sensors like folks are using on their telemetry equipped RC planes these days.

Honestly I so seldom watch my few restored TV's that component lifespan has never been a concern. Seems that most of us end up with a few favorite watchers, but for the most part there's not enough hours in the day once the collection grows past a dozen or so.

I decided to start work on the cabinet today. I removed the bezel and started to clean it up. I noticed that the "brass" area around the On-Off-Volume knob was quite well worn. It even has the thin plating worn off.
When cleaning the door the plating rubbed off with very little rubbing. And I mean very little. I then took all of the "plating" off. I thought Philco was the only one that skimped on the thickness of the plating. It looks like the aluminum door is bright nickel plated? Probably needs to be that way before it was brass plated. I guess I'll have to find a plating company to plate the door and the knob pieces. As a matter of fact, the bezel brass plating is gone along the most outer edge from repeated cleaning through the decades. I'll get an estimate on getting it all re-plated bright brass. Might even take my Predicta parts along too. |
