WTF! Amazing find, didn’t know these existed! Do you think that Accutronics tank is original?

Accutronics moved to Geneva, IL by 1971... then moved again to Cary, IL in 1982.
Hard to tell when this tank was installed

LOL @ Marshall encouraging people to stick their fingers into the chassis.

yeah I love that they put a knob on that internal pot. the dyno labels are awesome too. That reverb tank was born a few miles from where I was born!

Did this come out of Germany ?

Thank you for that info! Been trying to track down the history of Accutronics and date the tank in my black panel reverb unit. I’m assuming it wasn’t stock

Awesome find!
What kind of fuzz circuit is in these units? A Marshall Supa Fuzz / Sola Sound MK II Tone Bender?
