Admiral roundie alert in Boise!

Hey hey, looking good!

Same thing is going on with my Philco metal cab roundie, the CRT gasket has this icky goo coming off it but I don't care that much about it to go fixing it. Besides, the convergence is *perfect* and I'd kick myself if I disturbed it for something as trivial as lens cleaning. It's annoying- stupid free Philco has better convergence than any other roudie I own, though I have the CTC-7 very very close.

Yeah I thought about that too. If I do it it will be a while before I get to it. Convergence is perfect and I don't want to mess it up. I'm just tickled it works. Will need to degauss it though. Don't have the equipment to do it. I used my soldering gun to get most of it out but will need something more heavy duty.

You can make your own if you have enough BPC sets to tear up, that's what I did. Took the coil out of another set, wound it up in a 10" coil, then powered it with a transformer. You can't power it directly off the line, or you'll blow fuses. That's why I used a small step down transformer, I think it's like 18 volts at an amp.

Or you could wind enough wire to run it off line voltage, but it seems a safer idea to run it off lower voltage. Failing that, Ebay always seems to have some.

I may be able to borrow one. I'll wait till I move it to it's final resting place because you know it will get magnetized again. I need to figure out my focus control first. You have to turn it all the way to one end. I suspect the 1V2(focus rectifier) is not receiving any filament voltage. Does not light up as far as I can see.

Is there anyone who wants to sell a good 21fjp22a? I don't want to pay more than the TV is worth. Mine is a little weak. Its dim and blurry when first turned on. Takes 5 or six minutes to clear up and get bright enough. It's watchable for now so I have some time and not in a huge hurry.

[miniman82]

You have PM.

[John Marinello]

Did you test the CRT? Decent color tracking suggests the tube is fine.

So they were still manufacturing round-tube sets as late as 1967... Interesting.

[miniman82]

Yes, the Philco I got from Minnesota is a '67 or '68 model.

John: All the guns could be worn by the same amount giving a dim picture, and the tracking test will still pass as long as the current through each individual gun is close to the others. All tracking means is that all 3 guns are using the same amount of current, but even a tube that tracks poorly may still have a decent picture because all sets have screen controls for the purpose of balancing the tube out. I had an RCA supplement that mentioned the installation of a red screen control (most chassis had only blue/green) in certain cases where the tube refused to track correctly, in an effort to balance the thing out.

They made round tube color sets until mid to late 1969. Muntz, and a few private label makes. They sold them as leader models.
