Default Your oldest "over the top" audiophile story

I have to share this story. Someone at work had a grandfather (MIT) who worked on the original Trans-Atlantic cable. Anyway in the 30's he built a system (mono) of cascaded push-pull 45's with interstage transformers ending in a speaker mounted in a closet door as a baffle. He tested his oil bath capacitors by charging them up and shorting them with a screwdriver. He claimed the ones with the loudest spark sounded the best. I guess he was measuring the ESR in an indirect manner.

Um, three interesting sentences but, they have nothing to do with each other. What was your point?

Frankly I'm baffled that you don't get it. No hard feelings.

Peace -

I think he was testing the capacitors for the amplifier.

Perhaps that's the link between the cascade 45 amp and the oil caps...

I think it's pretty cool the kind of stuff old timers did to test their circuits in the old days. They probably knew a lot more than what we care to give them credit for, but just weren't published and didn't have all the killer equipment we got today.
