Commentary
Vacuum tube stereo preamplifier with 3-pole tube configuration for all stages.
The amplifier stage consists of a phono equalizer amplifier and a line amplifier, each of which uses highly reliable twin triodes. The circuit structure is a 3-stage K-K feedback type amplifier, with two ECC-83 and one ECC-82 in the equalizer amplifier section and three ECC-82 in the line amplifier section for DC ignition operation.
Equipped with MC cartridge booster transformer.
