Re: Record MegOhms AC generator
-Here's a Record Minor insulation tester next to a contemporary 'Wee Megger'. I think that i bought the former as a back-up in case of failure of the latter, but it turned out to be more of a curio. The Megger came back to life with replacement of the capacitor, but the Record is rather frail in certain areas (and for some reason does not use a capacitor..?)
As you can see it's quite large by comparison. The commercial success or otherwise can be judged by the Record s/no being around 7,000 and the Megger 700,000! They both date from mid WW2.
As far as the Record goes, apart from not generating proper voltage/current, the dog-clutch is iffy, the hand-crank chafed against the case in the past, which had a sizeable crack in it. No adjustment is available so i ended up sanding away the flange/lip of the bakelite where the two halves of the case meet, to avoid further damage! The lugs on the end of the case are where the carry handle was, apparently.
