Oh I don't know the building looks OK to me, courtesy of google street maps.
I have been checking out so caps or condensers to give them the term of the time.
All basically short circuit, the best i have managed to recover is a 2 mF but at 180 Volts it has 400uA leakage. So at some point I will melt out the bitumen on them and fit modern internals and then try to reseal.
I have some smaller mica caps that may test OK.
A long term idea for a project I think. time to get on with some smaller projects and get them out of the way.
