That was the plan, but my collection outgrew the case :D
I seem to be missing about 1/3 of the CRTs. Especially all the 3 & 5 inchers I pulled from scopes. All I could find was the ones that had their original boxes. I vaguely remember wrapping each of the loose CRTs in padding and stuffing them all in one big box. Where the heck did that box go :scratch2:

If I had seen these tubes being left somewhere, I, like my friend, Sandy G, would grab it all and squirrel it all away into the house! Im a total packrat, too!

If anyone is ever near Los Angeles and wants tubes like this, there's a place called Apex Electronics off San Fernando road in Sun Valley, which has 20-50 old round tubes (mostly p7 and p1 if I remember) in a dilapidated shack out back. I sorted through all of them one time I was there, and saw no regular p4 b/w tubes though. I haven't been there in over a year, so I can't say if they're still there or not.

Fair Radio Sales ran a special a few years ago on 1EP2s, or somesuch...It was a unideckar base (?) 1" optically flat CRT from some sort of military heads-up display, brand new in the box. I got one, & then some guy on the R-390 chatline wanted it, I sent it to him. He had some project he was gonna use it for, I wonder whatever became of it...I think I give $10 or so for it, I'm sure they cost Uncle Sugar a HELLUVA lot more than that...Cute widdle feller, though. Somewhere I have a book on CRTs, there was a guy, Sonny Clutter, who had an AWESOME collection of CRTs-Most of the pictures in the book were ones in his collection. There were some Wild 'n' Woolly lookin' Tooobages in that book...

Hah. Fair Radio Sales still has a bunch of CRTs including the same types I ordered 20+ years ago. Prolly not too many folks want these oddball tubes.

Is the Book "The Cathode-Ray Tube" By Peter A. Keller?... It also has the photo of John McQueen (with white shirt & tie) sealing the faceplate on a 30BP4, and the picture of the "DuMont lady" with two HUGE crts standing on end! I think we have have talked about both pictures before, and likely have copies of the same book.:scratch2:
Lots of crts pictured, many from the authors collection and other collections as well.

Note..On page 101 he shows the 1EP2 with a "unidekar" (no "c") hard pin base. Cute little tube, I have one with a G/K short after it warms up a bit. :(

Yep, that's the one...Think I got mine thru the "Electric Radio" magazine bookstore years ago...I misplaced mine, its here somewhere, I just can't find it, dammittall...I'm a book nut...Yeah, you can find almost any kind of info on the internet, but I've never seen anything approaching the variety, depth, & just good general info that this book has. Must have been a big leap of faith writing/publishing a book like that, I rather doubt many were sold...Not a lot of folks want to/care to know about CRTs..A few industry types, some academics perhaps, & then how ever many Keepers Of Odd Knowlege (KOOKs) like me there are out there...(grin)

I just checked Amazon... Not exactly a best seller..."Amazon.com Sales Rank: #4,168,051 in Books"... but there must be a few of us KOOKs out there!:yes:

Hi Guys,

Fabulous book and great photography! no vintage TV buff should be without a copy in his library.

That address went away when I retired from Tektronix. My current e-address is kellerp4@verizon dot com. New copies of the book are available for less than the used price.

Peter Keller

Welcome, Mr Keller ! You're among friends here ! (And fellow "Kooks"-grin...)

Ditto that! indeed KOOKs! :thmbsp:

I have been having difficulty getting a decent photo of one of my favorite tubes in my collection, the 2F21 Monoscope, used in early TV broadcasting to generate the "Indian Head" test pattern. This is about the best that I have achieved. Note that some paint was removed from the outside of the tube so that the pattern can be seen, normally the entire front of the tube would be painted black.

That's really cool. Was this used for a 5 trace oscilloscope ?


Wow! I've always wanted one of these :) I saw one months ago on ebay, but they wanted a lot of $$ for it.
