Oh yes, I know the current would be all wrong and actual measurements are off but I mean in the sense that I was able to check in practice that no sparks or shorts were occuring at least in those conditions, which make me comfortable enough to put new valves in. A bit like when you fit stabilisers to a bicycle!

Perhaps it's not a good method. My next project also involves 2x DF91s, so I may keep the dead DF91s I have for that purpose.
