Have a friend who was electrocuted to the tune of 120VAC into the temple, due to an open AC connection.
He was experimenting with AC motors for his turntable.
Something along the lines of him thinking (flash thought/reaction) about possible damage to his Kiseki Cartridge (!) ...as he went down.... (
Mein Leben! - Wolfenstein)
He is a known audio manufacturer and it’s his story, so I can’t give a name....
As for the LP12 Valhalla board, yeah, mine has got me more than a few times...
