Electronaut M63 Tube Microphone and Instrument Preamplifier

This preamp, M63 (serial number #014), was hand-built by Electronaut Company in Chicago and spent 8 years in New York City being rented out to various studios. Its finally back home and Im happy to see that its still in very good shape. I changed the three filter capacitors that see the most abuse, although the old caps still measured fine in terms of leakage once they were removed from the circuit, but why not get it in tip-top shape? I also replaced the top (slightly scratched) cover with a shiny new one, tested all the tubes, replaced a few bulbs, and calibrated the VU meters for 0VU = +4 dBu. A full suite of audio tests were made using an Audio Precision analyzer, and all audio tests met the usual specifications.

Noise was recorded over a period of about four hours, and everything passed with flying colors! This is a great sounding tube mic preamp in very good condition, reconditioned by the same guy who built it after 8 reliable years of service.

This unit comes with the original vulcanized-fiber flight case, ensuring it can be safely transported without issue. Electronaut has checked these preamps as luggage on flights and witnessed them tumble down a luggage conveyor, and there have been no problems whatsoever. (This particular unit was not checked as luggage and did not tumble down a conveyor, lol). This is a rare chance to get an M63 Microphone/Instrument Amplifier!
