Here are some pictures of the 10ee thyratrons at work (C16J tubes) in the
Monarch 10EE DC spindle drive.
The machine is 1968 and has the Module Drive.
If you wane see some realy big tubes:
Sorry, german only. But the pictures are still nice to look at. This is a 600

The person in the foreground holds a CQS 200 tube, used as NF preamplifier.
CQS 400 tubes in the background.
