This set has come up for sale nearby. I thought I'd give the CRT a test and see if it's any good before I make an offer. I can't seem to find anything on it so I'm hoping someone can tell me what CRT is in the set and what the test settings might be.

Thanks

its a roundie and they all test the same just use a 21FJP22 setting.

Looks like a '64 or 5, those are the best years for Magnavox color sets IMHO. I hope you get it, good luck!

Nice lookin' set ! Hope you can save it !

Thanks Sandy I'll do my best. I will go in the morning to do the test.

My B&K 465 tester calls for a setting of 6.3v for the filament and a g1 setting of 40. I'm using the settings for a 21FJP22 as suggested by Dave base on tubes of that size and shape.

It would appear that my tester is only testing one thing in the CRT. Will the results from that test be enough to determine that the CRT is good? I know there are three guns in a color CRT shouldn't they all be tested individually? Is it possible to get a good emissions reading from my B&K 465 and still have a bad CRT?

you should be able to test for shorts, cutoff and emissions on each gun. I am not checked out on that tester.

DaveWM · #8 02-13-2013, 07:19 PM

have you read the manual? from a pic I can see at least a shorts and emission test for each gun that should be good, I dont see a cut off but maybe that model does not check that directly. the Manual should cover all this.

IF you get there and it test weak DO NOT use any of the rejuv functions "just to see".

charokeeroad · #9 02-13-2013, 07:37 PM

Yes your right. I see this tester will test all the guns. I've never tested a color tube before but many black and whites. I'll sit myself down and read the color section of the manual. Any guess at the model number Dave?

DaveWM · #10 02-13-2013, 09:07 PM

model number? I don't follow.

charokeeroad · #11 02-13-2013, 09:23 PM

I meant chassis number

At least it's a nice cataract free crt. Don't dispair if it tests weak but seems to get better over some time. It may need a bit of a wake up! Hopefully it's a keeper 'cause that set sure is.

DaveWM · #13 02-13-2013, 09:36 PM

still confused, I thought you mentioned the model number in the thread title?

charokeeroad · #14 02-13-2013, 09:45 PM

Yes, I meant chassis number so I can look for a Sam's

Magnavox sets always seem to be a pain in the ass when it comes to finding the Sams for them. Seems I remember that you use "part" of the chassis or model number... and it will be listed in a "series" along with that partial number.... or something crazy like that.

It's certainly a nice looking set. Looks like it has a FBP instead of the FJP (since it doesn't need eye surgery). Yeah, if the tube test weak, just crank up the heaters to 8 volts. If the emissions come up nicely on the tester within a few seconds, you'll likely be in really good shape. If the meter is very slow to rise into the "good" zone, you'll have a lesser chance of a happy ending.

I'm guessing 1965-ish as well.
