Mark Levinson ML-7A Preamplifier - mc phono (L3 board), owned by ML engineer - $3,600 - (Hamden, CT)

This is a classic Mark Levinson stereo preamplifier manufactured when the company was still owned by Mark, back in the 1980's. It was highly reviewed by Stereophile's Gordon Holt at the time. It remains sought after, especially for its exceptional phono stage. This unit is labeled as an ML-7AL. The L stands for Japan export version, but all Levinson preamps have the ability to be switched for use with different international voltages and this one has been reset for U.S. 120VAC. Inside, it has the L1 and L3 boards (see photos). The L3 boards are the high gain 67dB moving coil phono boards (the L3A is 55 dB gain). I purchased this unit, along with other Levinson equipment, from one of the electronics engineers who worked for Levinson and then Madrigal Audio Lab and was involved in the design of many of their products. He lived in a town near me here in Connecticut, where the factory was based, but after the factory closed, he was moving a long distance and did not want to take all his gear with him. I have used it sparingly in a second system and have found it to sound excellent, but I have decided to downsize and focus on just my main system. The preamp main chassis is in excellent condition with just a couple of light scratches at one end of the top plate. The faceplate is perfect. The external power supply was obtained by the Levinson engineer as a cosmetic B stock unit and it has some holes drilled in the one end faceplate (see photo). It comes with the power supply connection cable, but no power cord is included. No camac connectors included, but they are available on eBay. Lastly, I had an electronics engineer friend of mine, who works in the audio field, go over the preamp, checking for proper voltages and gain and all was fine.
