picture tubes

[radio nut]

Fair Radio Sales in Lima Oh. currently has nos picture tubes, here is a quick list. 14BP4A,8BP4,23CP4,21YP4,21AWP4,21DSP4,21XP4,21AVP4 A,5ABP4,23ANP4,17QP4A,20HP4A,20DP4C,21VP4A,21ZP4A, and 23YP4.These can be tested before shipping, as of right now, none have been checked. They also have a lot of crt's. most are white screen ( I was told some of the military crt's were kind of green)Some of these may work in tv's, I do not know. If anyone would like, I will be more than happy to check for whatever tube you need. They do not put individual items in the catalog, only large quantities. Doug

Doug-

I am interested in the 5ABP4, or maybe more than one if they have them and depending on the price. I will send you a PM. Thank you.

I made a typo on that , it should be 5ABP1. Sorry, will that work?

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.

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

I would be interested in the price and shipping cost of the 21ZP4A.

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

Is 8BP4 the one that the little 50's RCA portable uses? if so, I could use a good one (mine has virtually NO picture)

Yes, mine came from an extra I kept around for my(1949?)motorola 9vt1. My set caught on fire so I do not need it. This tube is the only one That I myself have. I am not sure what is a fair price for this(I only know tube radio prices).So PM me an price. Doug

How did your set catch fire? Was it the ballast tube? Mine always ran hot around the ballast tube. The ballast tube burned out and that is why my otherwise restored set is temporarily out of service.

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

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.

No; not sure which one goes in the little 8PTxxx portables, but the 8BP4 is a round electrostatic tube that goes in the '49-'50 Motorola 8" sets. Same as a 7JP4 but 8".

I may have an extra tube from one of the metal 8" RCAs... Not sure, but I can check if you need. I have one I'm restoring, and one for parts. As long as the tube is OK in the one I'm keeping, I'd be happy to let go of the spare (if it's also good, of course)

The metal RCA portable uses an 8DP4 rectangular tube. The 8BP4 is an 8" version of the 7JP4. I too would be interested in a price for that 8BP4 tube since I have a Motorola 9VT1.
