The 21ZP4A did not test good, are there any other numbers that will work? some of the tubes I listed had 4 other numbers on the box, I just listed the first

Fair Radio has 2 used 8BP4's, one has surface scratches on the screen, the other is clean.I can check for price on wed.I have a new 8bp4. It was tested for 5 hours in a working set. I am a radio person by hobby, I do not know picture tube prices. If you want the new tube, Make me an offer.

a 5ABP1 will work fine if he likes green!

The 21AWP4 has no direct sub/crosses no other tube and of course I'm lucky enough to have a set with one that's weak. Another set of mine has a 20" rectangular tube that some clod ripped the base off of...IIRC the 20HP4 is a suitable replacement.

I will test them and get prices as soon as I can

I am not sure why my set caught on fire. After I put the fire out I got ticked off and pitched it. I wish I still had it. It's almost like I am jinxed as far as tv's are concerned. That set burned up. My next one is the one I have been talking about in my other thread.I can not get the picture to work correctly. So I grabbed a different set and the flyback is dead. I can get one, but In my years of working on tube radios I have never had problem after problem. It seems like I am not destined to own a running tube tv.But, it is my mission, and with the help of people in this forum I will make it happen. Doug

I think my luck is reversed.. I made the tv in my avatar sing.. Now ive taken on a radio project. a Delco R1128 and i am literaly scratchin my head over it.
Not to mention someone was in it before me and they left stuff hangin and i cant make heads or tails of it.. This is what they left me....

I should have at least done an Internet search before I asked about it. I found out the 5ABP1 is an oscilloscope CRT, and I cannot use it, but thank you for checking. What I am really looking for is a 5AXP4 or maybe an 8XP4, a small test-size CRT to use with chasses removed from their cabinets.

5AXP4s and 8XP4s come up on Ebay all the time for almost nothing.

TVs take a bit more time and patience to restore than a typical five tube radio. When I did my Motorola, I took it one section at a time. First the low voltage power supply. After all, nothing else will work without it. Next, the high voltage section and sweep circuits. This way, I could at least get a raster. Often times the set will work at this point but the signal circuits still have to be recapped. Restoring a TV is like eating an elephant, you gotta do it one bite at a time.

This 5ABP1 has tv picture tube written on the label (Sylvania I think)

They do have some used 10+12 inch tubes. I will start testing them friday. The bad thing about some of there stock are the part numbers. The majority of thier stock is military surplus. They have 10 inch dumont tubes they have 3,5,7,8, inch tubes all the way up to 20 inch(just a guess, I did not measure it) or so round pic.tubes, but they have military part numbers.I have to sort through these to find the hidden gems that we can use.Doug

[Mike Stamper]

I need a good used 12lp4. Are any available?

I've got access to some Military logistics data (all strictly Unclassified) and decided to pull the data for "P4" and "P22" phosphor CRTs. Attached are two PDFs with the raw logistics data. They are text searchable. Hope it helps!
