The GX-625 had much the same specifications as the GX-620 but with quite a few new refinements.
The pitch control, only offered on U.S. GX 620 models, was now standard on all GX-625 machines. Also, the GX-625 was the first Akai to feature an electronic digital tape counter, displaying not only reel revolutions but real time in hours, minutes and seconds. Unfortunately the reel-time display didn’t register during fast forwarding.
The digital tape counter also enabled electronic programming of auto-stop, auto-play and auto-repeat (block repeat).
These programmable functions utilized ‘electronic brake assist’ – during fast wind, tape flow would be gradually slowed to almost a standstill (using the eddy-current reel motors) but, as the desired spot approached, the mechanical brakes were invoked to bring the tape to an exact stop. A very decent mid-end tape recorder.
