Description
The Freeman Electronics
Corp. 729 N.Highland Avenue, Los Angeles California made this lightweight
(8½ lbs) battery powered, ‘Hi Fidelity’ semi-professional portable
recorder.
Three speeds (7½, 3¾ and 1
ips) with a (claimed) timing accuracy of 0.001%. 7½ and 3¾
ips were selectable by a shift lever, 1
ips necessitated a capstan sleeve removal. Fine speed adjustment could
be achieved using a lever in conjunction with the built-in stroboscope
and Freeman claimed a wow and flutter figure of less than 0.25% R.M.S.
at 7½ ips.
Drive was via a precision ‘military’ type motor with a centrifugal governor
and a four-stage, push pull solid state output gave 650 milliwatts audio
power.
Power was supplied by 6 AA penlight batteries or direct from AC cord
and the recorder could be operated in either horizontal or vertical positions.
