I recently brought this Racal 836 32MHz Universal Counter-Timer for £20 at Newbury Radio Rally last year. This counter is ruggedized military version of the 9036, has a fast warm up self contained 10MHz crystal oven oscillator option fitted and was made around 1972. When I first got the unit it wouldn't perform the self check facility and after being lead down the garden path I finally found several dry joints which were causing problems, re-soldering these fixed the problems. I managed to source an original technical manual from eBay.
Tubes are Hivac XN 13, all are soldered onto the plug-in driver boards.
