Our experience in repair began with vintage tube amplifiers and has since expanded into virtually all areas of amplification. It continues to this day to be the busiest department of the shop. K.I.A. services all amplifiers from vintage and modern tube amps to pro audio and hi-fi equipment.
As well as repairing, Joel Amsden manufactures totally Maine-made, military spec, hand-wired tube guitar amplifiers under his brand, SOMA Amplification.
