Mark Levinson ML-1 Stereo Pre-amp in working condition.

The Mark Levinson ml-1 solid state preamplifier Started as the JC-2 (JC stands for John Curl a technical consultant Levinson used for several projects) in 1974 the minimalistic sculpted ML-1 preamplifier possessed a timeless appearance with its slimline visual footprint and symmetrical control layout. As with all Levinson products the ML-1 is completely black anodized with white lacquer filled engravings. The ML-1 could be ordered with several encapsulated modules for different gain. Ads with all Levinson equipment from that era the connections were all of the Swiss Camac system and components were supplied by two Swissbased firms: Lemo or WW Fischer. As said before the active amplifying circuits where alle filled with thermal epoxy that acted as a heatsink and made in impossible to derive the actual circuit. Levinson stressed that the modular construction made nonprofessional repairments virtual impossible and solid blacks are easier to ship and handle than open cards. These is are mood points when one sees that the successor of the ML-1 the ML-7 uses open frame modules! The only other firm that uses the encapsulated modules for active circuitry and still does tp ny knowledge is the Jeff Rowland Design Group. The ML-1 is powered with an outboard powersupply the PLS-150 or later the PLS-151. Differences between those two are mainly situated around the better power regulation of the latter. As already stated the ML-1 is the succesor of the first slimline Levinson design the JC-2. According to John Curl, he and Mark Levinson had an argue about intellectual rights and the refusal the pay any royalties to him regarding the JC-2 and this resulted in a conflict between the two then the breaking of relations and a name badge change from JC-2 to ML-1 (Source available). The missing depth information that TAS (The Absolute Sound, one of the leading subjective audio magazines in the US) criticized the Levinson JC-2 for was alleviated by the new power supply according to Mark Levinson. TAS confirmed (issue 15) in a full report about the ML-1 that de depth information was much better now. Apart from the superb craftsmanship, its gorgeous looks, the modular construction, its outboard power supply and musical virtues the Levinson was unique in really one way: it had no peers at that time.
Completely modular plug-in construction. The class-A modules are changeable by the owner. The separate power supply (PLS-150) assures the lowest possible noise. Camac connectors are used for all audio inputs and outputs.
