Mercury Magnetics transformers are legendary for their stunning tonal superiority, build quality, consistency, and reliability. We believe in old-world customer service and single-minded product focus. Transformers are our only business -- allowing us to concentrate on providing you with the best-sounding guitar amplifier "iron" anywhere. We're also very proud to let you know that every transformer is handmade by us, using exclusively American components, right here in California. Mercury Magnetics maintains an on-going collection of vintage transformer components, building material, and machinery, in order to preserve period accuracy.

Mercury Magnetics founded in Southern California in 1954 and incorporated in 1968.

CAUTION! The voltages in your amplifier can be dangerous. Transformers and chokes are not user serviceable parts. Installation of these components should always be performed by an experienced technician. The simple ability to use a soldering iron is not enough to qualify a "do it yourself person." Those who are inexperienced in working with electronic circuits should never attempt to service their amplifier. Household line currents can be deadly!! Transformers, chokes and large filter capacitors can store a dangerous charge for several days or more after the amplifier has been unplugged. Never touch the terminals of such devices without being certain of their charge status. Risk of shock and damage to equipment may result from mishandling and/or improper use of these components. Please use common sense and always think safety first. After all, tone is most enjoyed when you are alive to hear it.
