Picked up and Admiral 20X122
I found this on my regional Craislist for $50 on Thursday. I originally decided the 3 1/2 hr trip[ each way as not worth it, but I emailed the guy Sat morning. He still had it, and I was on my way from south GA to northern South Carolina by 1PM yesterday.
The seller immediately assumed I was going to "flip" it and resale it for a profit asking "How much was I going to make on this set?" I assured him that I was a collector and was going to restore it and display it in my house along with my other sets. I had brought a buddy with me who restated that I have a collection of old TVs and radios in my house. Anyway, the seller said it hadn't been powered up in 30 yrs. He said the last time he used it, he let it sit for about a yr before trying it again. By then it wouldn't work. He said he reached in the back and was almost knocked off his feet. It's been sitting idle ever since. The cabinet is in excellent shape, no cracks, just a few minor scratches that Novus #2 should take out. All I plan to do right now is just check the CRT.

Yup, I'd make room for one of those.

Nice find and the price was a steal. You're lucky that it has the elusive metal back on it. That piece will often get more than you paid for the entire set - if you can find one.
After decades of passing them up I finally got a restored one a few months ago (for SUBSTAINTIALY more than you paid!) and am so impressed by it. One of my favorite pieces of my entire collection. As expected from Admiral, great solid performance too.

Every collector should have one of those, and you got it for a great price.
By coincidence, I'm working on one of the look-alike models (24A12) right now. Phil Nelson Phil's Old Radios http://antiqueradio.org/index.html

Those are great performing sets and you stole it! That set is an easy set to restore and the picture is surprisingly very good. Shine up the brass around the knobs and it's a very sharp looking little TV. Great find! Attached is the picture of mine that I restored a couple of years ago. I've got a 14 rectangular bakelite Admiral console still on my to-do list.

I would drive 3.5 hours each way to get one of those for $50, too. Nice find!

I'm waiting on parts for the Hoffman I'm currently working on, so I decided to try a slow power up with the Admiral on the Variac tonight. Surprisingly, I ended up with adequate sound, but no raster, just like the seller said when he last tried it 30 yrs ago.
I noticed the 6BG6 glowing blue, so I powered it down and checked that tube as well as the fuse. All checked ok. I checked the 1X2, an my tester showed bad, so I tried another one. Same results. 6BG6 still glowing blue. Have not put the HV probe on yet. AT least the set is not in too bad of shape. Funny thing. I posted how the seller stuck his had inside and was knocked backwards. The "Danger High Voltage" label is still on the set. I guess he ignored it.

If the entire interior of the 6BG6 is glowing blue (not just tiny, well-defined blue streaks on the glass), the tube is gassy, i.e., shot. Irrespective of how it may read on a tester.

Lucky guy. I have an imcomplete one that I got working, and, it broke down. They do show a very nice picture.

I've got too many other TV projects going now to start on another, but I couldn't resist the urge to pull the chassis out of the cabinet and have a look. It appears unmolested. I think I can only see one capacitor that's been replaced during the life of the set.
I'm waiting on parts for my Hoffman, and just about to finish up my Emerson portable with the picture jitter; so I may go as far as replacing a paper cap or two in this Admiral before I set the chassis back in the cabinet.

I didn't have anything to do yesterday, so I decided to start recapping this set. I've got most of the paper caps replaced and 2 of the 3 electrolytics done.
I'm still getting good sound but no raster. My HV probe shows only about 1KV of HV I started checking voltages in the horizontal section and found them way off. V15 the 6BG6 is as follows 6SN7 Horiz Osc V14 Pin SB I have Pin SB I have 1 -.5 0 1 -3.1 -10 3 9.6 2.4 2 100 38 6 190 105 3 -18 -6 8 260 221 4 -55 -24 5 190 120 Have tried another 6SN7 and another 5U4.

My voltages got messed up when I posted, so I will redo it.
6BG6 Pin 1 SB -.5. I have 0 Pin 3 SB 9.6 I have 2.4 Pin 6 SB 190. I have 105 Pin 8 SB 280. I have 220 6SN7 Pin 1 SB -3.1. I have -10 Pin 2 SB 100. I have 38 Pin 3 SB -18. I have -6 Pin 4 SB -55. I have -24 Pin 5 SB 190. I have 120

Ok, I have replaced everything in the horizontal osc & output sections with the exception of C71 (7.5pf @ 1500V) and the 500pf doorknob cap. I still have no high voltage. Most positive DC voltages on both the 6SN7 and 6BG6 tubes are way low except pin 8 on 6BG6 is right (about 270V). I have no negative voltage on the grid of the 6BG6. Replaced R78 and R79 and C54. I don't hear the horiz osc running and adjusting the horiz drive timrrer screw has no effect.
Any ideas? Thanks Doug
