That technician (who was deeply involved with the original design and manufacturing) graciously provided a massive amount of guidance and advice to ensure I built them perfectly. We emailed or spoke nearly every day. He even inspected and tested a couple to approve my work. I also rented an original to study to compare construction and sonics. Mine are built more cleanly and sound identical.I spent over a year chasing this dragon. I co-own a high level electronics repair shop in Austin, TX, and have professionally built and repaired TONS of studio gear and tube microphones in the last 30 years. I'm a fastidious, perfectionist kind of guy. I did all of the work myself. These units are built right, and I'm quite proud of that fact.
I built several that I'm keeping. IEC power cord for 120V operation is included. Photos are of the actual unit(s) you'll be purchasing, so look at the high resolution pictures carefully. These units are new, rack mounted once with washers. I sell too much stuff overseas and can't afford to be in trouble with the government in any country.The item "The Mastering Lab ML-1 tube microphone preamp" is in sale since Tuesday, April 04, 2017.
