Hi all. Just found this on Ebay. http://www.ebay.co.uk/itm/BALL-EFRATOM-RUBIDIUM-OSCILLATOR-M100-102-OUTPUT-10MHz-AS-IS-/232478267075?hash=item3620c8d6c3:g:i-AAAOSwC6dZrwtY It looks like lamp voltage 9.03V, in fair shape otherwise so probably is repairable but I can't afford postage. Has anyone else run into this set of faults, as it locks some of the time the problem might be bad 10K resistor on the lamp board, etc. Doubt there is anything major wrong with it and for my needs it could be fine. -Andre
