CTC-11 Found in WI

[Kevin Kuehn]

Brought this one home yesterday. I have a thread started over on ARF, but thought some of you guys would be interested in seeing it here. CRT tests strong on all three guns with no shorts. I'm not very enthused about dealing with the cataract.

my RCA data shows the 11 can use either the CYP or FJP tubes, looks like yours has an FJP. That thing is so delaminated, I bet it would just pop right off if you applied some gentle pressure. The ones I've done surgery to only had a little mold on the outermost parts, so they were still a pain to remove. I just break them off piece by piece with a screwdriver, it's back breaking but not nearly as dangerous as the heat method.

Yep, it's a FJP. I just noticed it's a model CTC-11C. If you break them off piece by piece, what do you use for a replacement glass? Sounds dangerous. This set came here from CA late 60's or early 70's, according to the previous owner.

All my sets have flat glass in front of the CRT anyway, so the lens doesn't get replaced with anything. You might be able to get a lens off someone on here, they get removed often, though rarely in one piece. Perhaps your set could have a flat glass installed?

nice set. you could do the catarac removal, look for the catarac removal procedure. if i did it any one could do it.

Don't break the glass. Like miniman said, that glass is close to coming off. There are mixed feelings about cataract removal on here and a few years back a member had a CRT implode on him from a heat gun. I have personally done a few with a 1600w heat gun with impressive results on and FJP.

Low heat and circular patterns. Never stop on one spot. Ever! From the outside in

I'm slowly restoring that same set. Mine has a slightly different CRT mask and with a BFP and separate safety glass. Should be a looker when its done. The 9 through 11 make damn fine pictures when tweaked out.

I'm glad that implosion concerns and cataract removal have been some hot topics lately! It would be nice if there was some outside vendor that could at least make the safety glass fronts for the 21FJ's. It's just an oversized dial glass! (okay maybe thicker) Seems like there should be some stock somewhere....there's been so many different shades of 'em from various manufacturers.

I'd sure be interested!

[miniman82]

Why not just make them yourself from plastic? It's not hard, just make a plaster cast of the CRT face then use a heat gun to form a sheet of plexiglass right into it.

if you do not fix the cataracts, the set will still look junk. if you are in this hobby, cleaning the tube is part of it.

Well sure... On your set the face had practically removed itself, that was some cateract! I'd bet that one was easy to take off....but the results looks good too!

You ended up following the procedure using the heat gun method and warming up the whole tube, right? As Doug has shown us in his videos?

That’s great to know there is another set like this in the works. Do you have any pictures of the set, or your restore to date?

I have no intention of breaking the safety glass off this CRT… there must be a better way. Time is no concern, so if a slow soak in some solution would work, that would seem a much better option. Last thing I want is glass shards all over the place. My wife would about disown me at that point. Not to mention I’d have a hard time living with myself if I ended up hurting someone in the process.

I’m a total newbie to working on a color set (have only restored two b&w sets to date), so I’ll be proceeding with extreme caution. I do have plenty of tube radio and audio experience under my belt, but this is a whole new adventure.

Thanks for all the comments and suggestions, I’m enjoying just having this set in my possession for the time being.

Was just thinking ...If a guy was to leave this set alone for another 50 years, the safety glass will likely finish removing itself from the CRT face. Anyone ever found one completely seperated? I suppose it would have been in a pretty nasty enviornment.

There were pictures of it on here at some point, but I think they were lost when the server went down when it was on the sub forum of audiokarma.

Right now the chassis is out of the set. When I get around to it, I will carefully remove trim and grill and refinish the cabinet.

that one will come off very easy.cut the tape and shoot some wd 40 into in starting at the top.it will work its way down.a little pressure from some wood shims will pop this one off.looks very loose.i did my last cataract a couple summers ago and it turned out very well.after dougs fiasco,i have personally vowed never to do this again.not the heat method.could soak it in a wading pool.good luck and that is a terrific find!
