hi all, i may have a line on a few 7jp4 crts but not knowing if they are in some demand, i dont know if its worth getting them. these are NOS without the boxes because they fell apart long ago. would they be worth trying to get at this point ?:scratch2::banana:

Yes, absolutely! They are always in demand since just about every 7" set uses them :yes:

I for one need two good 7JP4s for myself.

I wouldn't mind having one myself..

Great avitar!

Thanks :). She'll be at the convention next weekend for everyone to meet. Her hand is quite a bit bigger now four months on.

Aww heck, I could use one also....
If you don't want to persue them, hook me up with the seller please.

I could use one, please...:smoke:

We all could use one!!!! :D

:no:wow i didnt know they were that popular so let me see exactly how many there is and ill post if its good. this guy tells me he has several and they were all in the original boxes but the boxes rotted away long ago. he told me he had well over 100 crts for old sets all round tube and i was sick after he told me that after so many years holding onto them he decided to break all the crts to get rid of them except the 7jp4 crts, which means he had 21fb-21fj-and probably 21ax crts, im still sickened. he had got a dumpster to get rid of the crts that he didnt want anymore so i asked why he did that and he tells me , well no one wanted them and there was no market for them. he originally got them from a warehouse distributor that long closed and they needed them cleared out so he cleared them out and got all of them for FREE, YES FREE.

I would also be interested.

Would this be a bolt-in swap for the 7dp4 in your 621TS should it need a CRT?

I would never break up older NOS CRTs, regardless of size, shape or whether they were B&W or color. :no:

No, I don't think so. I have one of the 1911A11 bakelite Admiral sets, its CRT is OK, but a little on the weak side..

The 621 was perhaps the only 7" set that used a magnetically deflected CRT (7dp4).

Nearly all other 7" sets of the era used the electrostatically deflected 7jp4 or 7bp4, and adapting a electrostatic set to use an electromagnetically deflected CRT or vice versa is no trivial matter(it would require a total redesign and rebuild of the deflection and HV circuits of the set in question as well as the sourcing of scarce specialized parts).

Ultimately, I may just have to be satisfied as one of the lucky few who HAS a 621.. Seems like somewhere I read that there are MAYBE 150 examples remaining.. I spout off about my good fortune to the local yokels here who AREN'T "TV people", & they just smile & say, "That's Nice..."

My Admiral 19A11's CRT is ok, but not great, so could use one if they are good!

Like the money from buying all the latest crap.

does anyone know what the number test reading on a bk440 crt tester for a NOS 12kp4a crt. i know what a used 12lp4 reading was when i had one but this kp4a is new and i just want to see the difference between the 2, used and new. i also checked it on a bk 466 but that just has a large scale for bad and good which was way up on the good and passed all the other tests as well. the scale on the bk440 goes to 1000. only thing with this crt is it needs new dag. where do you buy this dag in a spray form ? also is there a date code on the crt cap, mine shows 5822 if this means anything or how could i know by these numbers what year it was made, ita an rca crt.

I would be interested in a NOS 7JP4, too.

P.S. To find spray-on aquadag, do an Internet search for "Slip Plate" or "Aerodag."

The B&K 440 isn't exactly a precision piece of equipment so I wouldn't worry about an exact value. Just well into the green would be fine.

Zoro is the cheapest place I know of for Slip Plate: http://www.zoro.com/g/00058307/k-G2655791.

Grainger has it too for a little bit more: http://www.grainger.com/product/SLIP-PLATE-Dry-Film-Lube-1WVK7

You can add me to the list of people interested in buying at least one NOS 7JP4.

With all this interest, I'm sure you can see that it is definitely worth your time to get them.

i have to tell you guys im really sorry and im disapointed in the fact that i was instructed where these 7jp4 crts would be but unfortunately there were none and to the owners surprise he now thinks that an fellow from long island ny stole all of them. the crts were kept in a lock building with no supervision and just given the keys to look for what ever he wanted. this fellow would come up a few times a year to this antique shop which has several buildings and he would let people go and look and grab what you want and trust you would go back and pay. so since this fellow has come around they are all gone and i hope the person chokes on them for stealing them. but i am going to still look and again i am sorry but in the begining i was not sure as it was to good to be true. so all i got is a NOS RCA 12kp4a crt, so ill be on the hunt.

Too good to be true. I knew it.:smoke:

I had a bad feeling about this . . . . RATS!

No surprise to me. I was just waiting for the ending and it was as expected.

Well guys, back to your hunt...

im sorry guys but i did say in the start of this thread that when i see them i will believe it and this man is old so anyone could have taken what they wanted and he would not have known. he does still have several tv sets like table top motorolas 7 inch i think 2 of them and an old projection set and a few other 12 inch sets. this would have been alittle harder to steal but 7 inch crts can be put under a coat and not seen.
