M2 Circuits services analog audio gear from tape decks to receivers. Owner Maurizio worked at T. M. Electronics for several years under the guidance of a former Studer/Revox, TEAC/Tascam, and Marantz technician.
Things we service include reel to reel tape decks (full repair, head relapping, calibration using MRL calibration tapes), cassette decks/recorders, receivers, power-amps, preamps, tube gear, guitar amplifiers, and even vintage test equipment from Fluke to Heathkit.
For more detailed information about repairs to reel to reels and cassette decks see our Tape Recorders page.
For more detail information regarding guitar amplifier servicing & repairs, please see our Guitar Amplifier page.
We use top quality parts and will never hesitate to let you know when something is ‘audio-foolery.’ Components are sourced from reputable suppliers like Digikey, Mouser, and Farnell/Newark. Brands used include Nichicon, Panasonic, Rubycon, Vishay-Dale, Yaego, Stackpole, Pomona, and more.
Test equipment is maintained and aligned, and of well known and trusted brands like Fluke, HP/Agilent/Keysight, Tektronix, Hickok, Heath, and BK Precision. Some test equipment has been custom designed and built by Maurizio himself for the sole purpose of testing audio equipment.
If you have gear that you’d like to have looked at, feel free to email us at email@example.com or submit a repair inquiry through our contact page.
We do not work on any Sony tape products.
