Hi and welcome to Hill Amplification. We are located in Zumbrota, MN just north of Rochester. I've been a electronics service tech for over 20 yrs and I work in the industrial processing field. I've been servicing amplifiers since the late 70s and building amplifiers of my own design or clones of classic designs for over 15 yrs.
