That crt is almost certainly an RCA, code 274 I think it is? It wasn't until later in the decade that Admiral made its own color tubes. I think the DuMont that was mentioned was a rebuild.

Stunning good find! I always thought that control panel was a great idea!
May the old TV Gods smile on you for saving it!

I'm always happy to hear of a rescue! Can't wait to see more photos! Only "did" one Admiral, an early 25" Canadian model with "scrulox" square head screws (pain in the butt), that I fixed up with a new CRT for a friend at college. It was passed down to different members of her family until it "smoked" years later. Good pix and performance while it lived.

Well i've spent some more time cleaning controls and tweaking adjustments, I have color now and closer to a white balanced raster, but i seem to be having a focus problem, here is a picture update. Logan

Looks good for day one. Have you tried cleaning the 1V2 focus rect. socket? Had a hell of a time with mine, also had bad connections at the CRT pin and some bad resistors. Got a whole new fly and started from scratch. Good luck!

grey scale looking good! check that focus tube and crt socket and pins. i think you may have a huge save on your hands.that is a great set.

Focus has been my problem, too. I found a good "tough-dog" article out of a 60s trade magazine that covered a poor-focus Admiral. While it didn't really cure my problem, it did teach me a lot about the circuit. I need to dig it out again. My problem swirls around high regulator & HO tube currents. I changed my flyback (the old one looked terrible and ran extremely hot) but I'm still overlooking something, maybe a resistor somewhere? I'll be paying close attention to your progress!

After some investigation of the crt, I think my focus problem is caused by the PVA layer of the safety glass. I think it has turned milky white. I examined the front of the crt with a magnifying glass and i can't see any tricolor pixels, but i can with my other tv sets. When Doug or someone comes up with a new and improved cataract removal proceedure. I think mine will be a good candidate. Here are a few more picts 1 is a close up of the front of the crt. Logan

try your focus control and see if you have enough range. if so.then its that safety glass. as bad as that appears to be,it just might fall off!when you get tired.i will buy that set from you.awesome find,at worst you might need a crt.at best,could be a resistor or the glass.anyway you go,you win!

Doug's method works well, I just would never try it on a 23EGP22. Wear a safety shield and heavy clothing and you'll be fine. I think Ron's right, the way it looks, it might fall off! I have also heard of soaking it in diesel fuel for a few days, a guy I was talking to at the ETF told me that, says it worked for him. Good luck and I'm jealous of that Admiral,
you just don't find the round ones anymore.

I think I would use a High voltage probe and actually check the High voltage and the focus voltage. Looks like you have a low focus voltage. I see the cataract on the crt, but you have a uniform out of focus picture. High voltage should be about 25KV and the focus should be around 5KV. If high voltage is low, the focus voltage will also be low. Check the focus control it should have a noticeable effect even if the glass is the issue. You may have a bad focus rectifier tube, or socket. I have also seen defective crt socket cause bad focus. The focus coil itself could be bad as well. You really need to know what the focus voltage is first.

The model # LD2179D and the tilt-out control panel suggest a high end 1965 model. Nice find.
