in the USA as Roberts 770X).
The M-8 had the same basic layout styling as
its predecessors the Akai M-6 and M-7, and like the M-7 it had the exclusive
“cross-field” biasing system.
All of these early “M” series Akais
utilised valve circuitry and a continuously variable playback equalisation
This was a quarter track stereo recorder with
internal power amplifiers and monitor speakers. A single motor was employed
for all transport functions and the maximum spool size was seven inches.
The twin monitor speakers were mounted on the
top of the cabinet and stereo sound was really only available near the
recorder. At greater distances, the stereo effect was completely negligible
and widely-spaced, wide-range remote speakers would have been necessary
for normal stereo listening.
Three speeds were available with the use of
a capstan sleeve (7½ ips – 3¾ ips without
the sleeve and 3¾ ips – 1
ips with the sleeve) but according to test-bench reports of the
time, wow and flutter were higher with the capstan sleeve fitted.
