Description

A portable battery-operated recorder from the early 50’s, the EMI L2 was a single speed, single track recorder designed for use “in the field”.  It took 5″ spools, used a permanent magnet d.c. motor (governor controlled) and had a manually operated (cranked), geared rewind.

The batteries used were 2 x 67.5 volt Ever-Ready type B103 for H.T and 10 x 1.5 volt cells in a removable metal box for L.T. (valve filaments & motor).

There were two heads, record and playback. No facility was provided for erasing, so one would always have had to use blank or pre-erased tapes on the job.

Power consumption was 12 mA on record (H.T.) and approx 800mA for the motor and filaments (L.T.)

Three models were made, each with a different tape speed – L2/C (15ips), L2/B (7½ips) and the L2/B (3¾ips).

In 1960 the L2 evolved into the solid-state L2/TA , identical to the earlier L2s but transistorised. A further variant was produced, the RE321, again mechanically identical to the L2.

Finally, In 1965, the aging L2 series was replaced by the all new Model L4.
