My first 'real' studio was the campus radio station where I was dutifully assigned the job of rebuilding a ton of old broadcast junk - they wanted a few extra desks for the students to do spots.
Missed a cap on one if I remember, Might've zapped a student or two..., but got a good grade of the course...
Them old step-attenuators are worth their weight in gold!
Uh, yeah... I despise cart machines....
