So I had a bit of a problem crop up while restoring a Tektronix 224 scope...
While removing the CRT, the plug housing came apart and all the pins fell out and I don't know what order they go back in.  |O

Is there anyone who has a Tek 222 or 224 portable scope who can pop the cover off and take a few photos?

I know what pin numbers each wire is supposed to be for, but I don't know what the actual pin numbering is on the tube itself to match to the wires.

Any help would be awesome :)
Where does all this test equipment keep coming from?!?

Here are some Pix taken this AM.
There is a single white wire in the dielectric shield at about 1:30, unused pin/space on either side, probably anode or focus if anode has its own HV connector near the screen.
Numbering starts just past 3:00 with a brown stripe in gray jacket and proceeds clockwise, red, orange ... to gray stripe before the unused pin/space back to white.
I did not remove the socket from the CRT.
I can send more if needed.

Awesome, thanks for the help :)
I found some pics, but this helps confirm I got it correct.

Scope CRT is now back up and working again. :)


Here's the pinout attached below if anyone else happens to be looking for it in the future.
