CRT pin crimper ?
 

I've seen CRT pin crimpers mentioned in this forum a few times before, but never actually saw one. That is until I spied this on ebay recently. At least the seller described it as a pin crimper :scratch2:

Can anyone verify what it is and how it's used ? I'm just guessing in these photos.

What is it that would need to be crimped on that tube socket?

I used one, just the way you're using it. I think the intent was using the chrimper, instead of resoldering the pins. :scratch2:

Yes, that's my understanding too. I guess if you're out on a service call it's a lot easier to crimp than solder :)

I was given one by a retiring repairman, and if he hadn't explained what it was I would have never figured it out. I've used it a few times. Resoldering pins can be tricky sometimes, it doesn't always want to flow right (my experience, anyway.) One issue with these is they are permanent-forget about pulling that socket off after doing this.

is there any part number or company name on that tool ?

Any chance of borrowing one sometime? I have a 21FJ that measures open on the filaments - very suspicious, but I have had no luck with soldering.
I have another 21FJ that is fine and appears to have been crimped.

Edit: the posted image shows a patent number (first two digits hard to read)
PAT.
xx78698

PAT 2878698 is the only marking I see on it. Yes, I suppose you could borrow it sometime.

They reffered to it as "The Burns Perfect Pin Crimper". The old electronic distributors sold them in the late 50's and 60's.

So thats what that thing was !

Had one at the shop. Saw it for 30+ yrs but never asked what it
was. Was in a drawer with other odd ball things nobody used.
We always just soldered the pins.

I want one!!!..

So do I.

I'm surprised that with all the dozens of loaded tube caddies I've bought over the years that I've never seen one of these before.

Hi
I used to carry one of those in my caddy, it was used to crimp the pins on the CRT and other tubes. Some times the 6CD6, and other horiz output tubes ran so hot that the solder would "unsolder" and you could crimp the pins and get a few more hours out of them. Also there was a time when the 5U4 pins were not soldered well and I used this device to crimp them. At one time some of the tubes were not soldered very well and it came in handy. I am talking about 1960 to 1963 when I was in tv repair. :yes:
