I'm working on a Admiral 20X11 N, Does anyone know the values of 2 resistors on the 1X2 socket? (Can't read the faded colors anymore). I also need the value of the Doorknob cap and suggestions for finding a replacement, This one's dead. Thanks!

You can find the schematic here: http://www.earlytelevision.org/images/Admiral-20X1-20Y1-20Z1-Sams-100-1.pdf

The filament resistor is 3.3 ohms and the resistor in the HV line is 1 megohm. Very often I find the series HV resistors are bad, so definitely a good one to check and replace if necessary.

Great! Thanks for the info and schematic! Of course I have a thousand resistors and never the values I need.... I'll track down the parts and post the progress and photos of the TV. Stay tuned...

Here's the current progress. I replaced all the wax/paper caps, replaced a few out of spec resistors and tubes. There is a slight tearing at the top of the screen and the focus is off a little on the edges of the screen. The main issue now is that loud Video buzz coming from the speaker, Even with the volume turned all the way down it's there. Is this common with these early sets? Adjusting the contrast doesn't quiet it down very much at all. Any ideas? I haven't replaced any lytics yet.

This is a shot in the dark regarding that 'buzz', but try turning the vert. hold control to make the pic roll. Or disable the V.oscillator momentarily. Does the buzz change at all? I've seen a few cases where the vert. pulse was getting into the audio.
Replacing the electrolytics it will probably clear the problem in any case.

Good looking critter:thmbsp:

Problem was a 3 section electrolytic can. I replaced the Electrolytics and the video buzz went away!
Here's a youtube video of the set before and after the video buzz issue: http://www.youtube.com/watch?v=LiYqoikrEXk

Very nice :thmbsp: I'm currently tweaking a 20X12 and you've set the bar high for me :yes:

I believe the 20X11 has an ebony cabinet and white mask while the 20X12 is brown and gold. Otherwise identical.

I was lucky and only needed to replace caps and a few resistors. I wish I had the equipment and patience to do a proper alignment but I don't. My cabinet is crack/chip free and barely any corrosion on the chassis, must have spent it's life inside a climate controlled home. And yes the 20X11 is an ebony cabinet.

That little set is just cuter'n a bug's ear.:tresbon:
