Ah yes the Milty Zerostat (anti static gun). It was red. Good times.
My older son (now past thirty) as a tyke turned up the volume all the way, gave us heart attacks and blew out my beloved three way Braun (810?) speakers. Amp was a Marantz, TT was a B&O, Tandberg Cassette Deck and hardware store 16G wire.
Fun to remember.
