Technics SU-8600
Technics ST-8600
(1975 - 1978)

Six independent heavy-gauge windings, constant current structure, two 15,000µF caps for the SU-8600. Differential amp, modified SRPP and low-noise transistors make the phono stage. Differential amp, emitter-follower, voltage amp and independent stabilized power supplies make the output stage. Current mirror circuits are used in the first stage, diff. amp stage and 3-stage tone control circuits.

Flat group delay ceramic filters, 8-gang capacitor (5 for FM, 3 for AM), two-step muting and direct FM-to-tape recording for the ST-8600 tuner. FM-to-tape means that the play/rec tape terminals are on the ST-8600 to bypass the amplifier loop ; the pre-emphasized broadcast signal is recorded and played back through the tuner's de-emphasis circuit to recover the original flat response.

Solid silver chunks of 1970s hi-fi with excellent industrial design wich Technics sadly turned to brownish matte black in 1977, swapping the warm wood for optional rack adaptors.
