90 volt battery eliminator

[Yorkie]

Thanks for the feedback Rob - sounds excellent - the best solution yet, provided the current capacity is sufficient for whatever set it's desired to use it for. I guess it would be no problem with the low consumption DKxxx DFxxx series of B7G valves. Chep enough too - as you say, as cheap as a stack of PP3s of dubious capacity from the pound-shops.
