(Back in 1963 the father of one of my school friends was a Director of AVO's and arranged for me to to have a tour round their original factory in Vauxhall Bridge Road (London). It was a fascinating collection of adjacent, originally houses, that had connections knocked through at all levels, with bits of production all over the place. They made the Douglas Coil Winder there as well. Very shortly after then they moved to Dover where I think they still are)

Ah. Nostalgia kicks in ....  :thumbup: Still got, and use, my AVO8 Mk4  :bow:   although not on resistance. Don't think the 15V battery is ( readily ? ) available now.
Happy hours in the RAF skiving on the AVO valve tester .. waiting for the heaters to warm up  Quick shufti at the Good / Bad meter. Good 'uns to the box marked 'Tested  OK'. Otherwise back to the maker. Stick the next in  .. light a fag .... wait for heaters etc ..etc.. etc ...

15v batteries for avos easily available on good old Ebay!! I have an AVO8 mkV and a little GPO AVO 12D. they are the best!

seadog:
You only need the 15v battery for the high resistance, 20MΩ I seem to recall. The rest just use 1.5V.

It’s been a while so just a very quick update I pulled the cards and found that one of three cards was missing a piece of electronics ( right side three down )
