Technics SE-A5MK2 (1984)
The SE-A5MK2 is a stereo power amplifier from Technics, introduced in 1984. The surviving record is thin. No full brochure, manual or measured bench test appears to have come down to us, but the period press got the essentials.
High Fidelity (April 1984, p.37) noted its introduction in a roundup of new power amps. HiFI-Stereo (June 1984, p.55) reviewed it as a 150-watt-per-channel Class A design priced at $800. The review described a "Power Linear Circuit" meant to handle low-impedance conditions. It also put the amp's weight and size down to the heat that Class A biasing generates. The amp could run in stereo or mono.
A smaller sibling, the SE-A3MK2, shows up in a later HiFI-Stereo directory (February 1987, p.91) as another Class A DC power amplifier. That suggests the MK2 line was a family of large, heat-throwing, high-current amps. Exact production years, detailed specifications and owner history for the SE-A5MK2 itself remain undocumented.
What the record solidly shows:
- Stereo power amplifier with Class A output stage
- 150 W/ch; $800 in 1984
- Power Linear Circuit for low-impedance loads
- Heavy chassis with extensive heat sinking
- Operable in stereo or mono
