  1. 2 x e/m deflection tubes.
    2 x critical potential tubes
    1 x triode
    2 x fine beam tubes
    1 x Perrin tube
    1 x maltese cross tube.

    May have instruction booklets for them.

    Have not tested any of the above; will only do so if interest is shown.

    £200 each, buyer arranges transport/postage. Discount for bulk orders. I will be in London evening of 10th November.

    I can make one, or use a helmholtz, but the real one fits in the stands with the tubes.

    Hi Mike, sorry been on half term. Any Chance you can provide pics of the 2x fine beam tubes?
  8. I just saw this too, we'd be interested in the Triode, Mike.

    Not wishing to start a competition, well ok I am, I have been offering triodes for sale on here for a lot less for over a year. The ones I have are the fully evacuated not the gas filled, and I have full instructions and current packaging thanks to 3B.
  10. Haha, sorry Nick my brain hadn't absorbed that info for some reason..
    Sounds good, I'll PM you.
  11. Is a fine beam tube still available?
