Description

A pretty spectacular sounding machine that Anyone considering would best ignore the specifications for frequency response w/f etc. as it sounds way better than many very expensive Japanese machines. really musical, really dynamic and very small for a 10 inch capacity machine. As you can see in the photos, I added an IEC socket for power and RCA’s for input-output.

Available in two track (728) and quarter-track stereo (748), both versions had the following features:
Monitoring: Phone jack on front panel for head phones.

Approximate dimensions 18 inches wide 14 inches tall 14 inches deep. Weight 50 pounds. rewind/fast-forward 1600 ft./m

Headphone jack, early remote control option so the 728 can be started and stopped in any mode of operation.

Inputs for high impedance or low impedance microphones x 2

These machines had an optional fourth head, switchable on front panel, for quarter track playback which unfortunately my model does not have.

Additional Info

at customer’s option. Record head and reproduce head. full track, half
