Akai GXC-325D
1975
1977
The GXC-325D is one of the well remembered 1970s cutie design recorders - it also was one of the most successful, sales-wise.
Despite its two-tier looks, hardware-wise, what makes it a recorder is far from the gadget or the looky-looky : closed-loop dual capstan, 3mm capstans, 7,7cm flywheels, a bigga AC servo motor with 40 teeth on both rotor and stator and three GX heads which last forever forever forever.
On the electronics side : dual Dolby (rec and play circuits separated), ADR circuit for automatic recording equalization (less IMD and high frequency distortion) and a (switchable) limiter circuit make up for the features lost when downscaled from the GXC-570D or GXC-760D.
Also in are a Hall IC commanded end-of-tape auto-stop function, a pause switch keeping the heads on the tape, a "tape run" indicator showing with a few blinking LEDs transport mode and another LED for +7dB peak input level.
Bar the bottom plate and lightweight (but made of real plywood) plinth, there is very little plastic here : cheaper decks came in at 9kg in the 1975.
And they did and still do last forever forever forever.
