Teac A-2300

1 9 7 0 august 1970
1 9 7 2 1972

Mid-end recorder built in a very solid way :
1970s style.

Single-piece diecast frame for the front and sides, three "hyperbolic" permalloy heads with 3-stage dc playback amplifier, automatic tape lifters, three fan-cooled motors, adjustable turntable height for both reels and an ingenious braking system with "drums" and "shoes" à la SP-10MK3.

Also in are the usual mic/line mixing, tape/source monitoring with 0,15s delay, high-bias position for high-output / low-noise tapes, mono/stereo recording and counter derived from the supply reel.

Replaced by the taller A-2300S and A-2300SD in 1972 or 1973 depending on market, both doing away with the cute but retro "pause" lever and the two-in-one VU meter.
And adding Dolby deemphasis for the A-2300SD.
