Re: RCA Telebision

...And now for another episode of Where Are They Now...

Y'know, I had forgotten about this thread, but just did a quick search and sure enough-- here it is..!

See, just this past Sunday, I encountered this very TV set at a hamfest. Yes, literally, this TV. ...'cause Gonzo was the one selling it. :-)

Anyway, I had passed by this set a few times on my rounds of the hamfest flea-market (mostly trying to find some excuse not to buy this thing, even at five bucks). I stopped by later on to take another look at this set, and got into a conversation with the seller, who turned out to be none other than GonzoTheGreat here at AK..! Long story short, Gonzo simply gave me the set just so it would have a new home. [Thanks again Gonzo!] Gonzo mentioned the bad HV, but I hadn't yet realized he had actually asked about it here on this forum.

After I got home and got around to popping the back off this set, I immediately noticed that the fusible resistor looked pretty fried, which an ohmeter demonstrated was indeed the case. I popped in a new one (I happened to have a few NOS ones around), and made a few quick visual and electrical checks (turns out to be a pretty clean set, really), and put the set on a variac to let it 'cook' for a while. Then I turned 'er up to 100%, crossed my fingers, and everything came up a-okay..! I kept waiting to see if the B+ supply would blow the fusistor again, but it never happened. The HV section seems strong, with no arcing or hissing, and no signs of blooming. I put on a pattern generator, and saw that the picture geometry was excellent! Other than a few minor things, the only real issue I noticed was weak IF (turned out the first IF tube was gassy; a replacement took care of that problem). [It's aaliiiiveee! Ah, isn't it just neat to see something broken become usable once again..?]

Anyway, I was going to PM Gonzo just to let him know (though now he probably wishes he had kept the TV..!), but then I started thinking-- didn't Gonzo actually post about this set a few months ago..? :-)

By the way, to answer a few of the questions that were asked about this set, it's a KCS-130. The latest date codes on the apparent "virgin" tubes in this set (at least those that have date codes) are 61-52, which suggests this set was made in early 1962. This set still has a 17" picture tube, though; hadn't those pretty much been replaced by the (more square-cornered) 19" tubes by about that time..?

Edd-- I too had noticed (and wondered about) the oddly-designed multi-turn pot, and you're right-- it's the horizontal hold control. Thanks for the info on its design!

Assuming I did it right, attached is a pair of images showing the set in action.
