Valves wanted.

I am always on the lookout for all sorts of valves to enhance the collection/museum. Of particular interest are:

  • CV and British military (Ax, Nx, Vx) marked valves and CRTs not already in the collection - in addition to those mentioned below
  • WWII cavity magnetrons - I am particularly interested in earlier types e.g. CV38, CV41, CV108, NT98 - but also want to add any not already in the collection
  • 1Bxx series valves etc.
  • Engineering sample and production sample etc. valves
  • Sources of information on the valves in the collection or on the equipment that used them
  • Anything unusual!

Other than the general statement above, the following is a list of wants gleaned basically by reviewing documentation - NB it is not a 'total' list of what I want (see above!), and the list changes from time to time so please check back later.

This column was updated 14-oct-2013:
  • Any engineering or production sample (etc.) valves.
  • Any examples of German WWII magnetrons etc.
  • Any of the more unusual Wehrmacht valves not already in the collection
  • Any silica valves
  • A Resnatron
  • A Type 43 valve as used in Chain Home! (well, one can hope!)
  • A small mercury arc rectifier (got a big one already) and any ignitrons large or small
  • Any exotic very-high voltage valves
  • Any balloon-shaped transmitting triodes/rectifiers (e.g. like the MT9L)
  • Any CAT, CAM or CAR cooled-anode valves
  • One of the larger type of Image orthicon camera tubes

If you have anything for sale/disposal/trade, let me know. Donations always welcome!
