Unidentified Tube - One for the detectives!

Nodric · 14th October 2011, 02:01 PM

My first post...

I picked up a whole array of old gear from an estate of an ex engineer, and along with the box of tubes came the one in the attached photos. No identifying marks on it, and despite my efforts I can't identify it.

Thoughts?

I really know nothing about tubes, but it looks like a cathode ray tube to me.... Someone else will no doubt say what it really is

Not a CRT, or at least I don't think so. The screen (amber lens) is only 3/4" across, and a total of 1" if you include the tube width.

I hope it's some sort of fancy indicator I can hook up alongside my Magic Eyes

Either a CRT, or a TV camera tube. I suspect the latter.

Undoubtly a 1" camera tube. Not an an indicator, sorry !
Google for "vidicon".

This reminds me of the old vidicon (video camera pickup tube). They were used in video cameras before the days of CCD pickups. Not sure what to do with them now but back in the day they were worth a lot of money.

Yep mystery solved. It is almost certainly a vidicon tube. Worth squat by the looks of things, and not much use for a project

I did get a pair of matched 807s, and some 26s, a pair of 12ax7s, and some others I need to look up, including a 5632/C3J which seems to have some value.

Someone who collects old TV cameras might be interested. There are certainly folk in the UK who do that, and I guess elsewhere too. It will never be made again, so don't bin it!

No fears on me throwing it out, I learned my lesson years ago about binning stuff, and now cry (metaphorically) over the stuff I threw away. I remember junking dozens of Mullard tubes (including the good stuff)! Used to think it was funny to throw them at walls! I was young at the time...

I use to play flying saucers with my granpa's pre-war 78's and watch them smash to bits...
