Seller's Description

Melos MA-110b Tube Stereo Line PreamplfierI believe this is from the early 1990s, 1993-4 or so. I believe it is a hybrid design and uses two 6922 tubes. IT has two CD inputs (CD-L and CD-H) for different amounts of gain since at the time CD players had more variation. Also note the Phono input is just a line input marked as Phono -- you will need a phono stage.NOTE: Selling As-Is -- works and sound decent but there is some intermittent light crackle. You may need to go over this and check for any issues. I think it was once looked at by a tech and had a couple components replaced, but I don't think it solved the issue. Was a long time ago and my memory is fuzzy. Still, could be a fun project.Condition is decent with some scratches as shown.Any questions please let me know, and thanks for looking--

About Line Magnetic Audio

Line Magnetic Audio: Brand Overview

Line Magnetic Audio was established in 2005 in Zhuhai, China, by brothers Zheng Cai and Zheng Xi, both passionate audiophiles with deep roots in tube electronics. Zheng Cai's background as a former general manager and chief engineer at Cayin, combined with years spent studying and restoring classic Western Electric, Altec, and Jensen components, provided the technical foundation for the company. This heritage of reverse-engineering and understanding legendary 1950s American audio design remains central to Line Magnetic's identity and philosophy.

The brand specializes in tube-based electronics and speakers, with a product range spanning integrated amplifiers, preamplifiers, power amplifiers, DACs, phonostages, and horn-loaded loudspeakers. Line Magnetic is particularly renowned for its meticulous replicas of classic Western Electric, Altec, and Jensen designs, as well as proprietary field-coil drivers that have earned respect among both manufacturers and DIY enthusiasts. All products are hand-assembled using point-to-point wiring across two factories, reflecting an uncompromising manufacturing philosophy.

Line Magnetic occupies the high-end boutique segment, targeting discerning collectors and audiophiles who value vintage-inspired design married with modern engineering. The brand commands respect for its scholarly approach to audio history, rigorous material research, and unrelenting build quality. Rather than pursuing mass-market appeal, Line Magnetic has cultivated a devoted global following among those seeking authentic tube sound and meticulous craftsmanship.
