Additional Details


In 1972 Akai replaced the
3-year old 4000D with the new 4000DS. It was an economy deck but with
a performance to match and even exceed professional machines of a few
years earlier. Speed change was via a slip-on capstan sleeve and a rocker-type
equalisation switch – clumsy but economical.
One of the most interesting features of this deck was the lack of pressure
pads. It was unusual to find a budget machine designed with a tape transport
system so good that pressure against the rear of the tape could be dispensed
with.  The advantage in reduced head wear was obvious and there was
no increase in drop-out, which might have been expected from this arrangement.
