A very old recorder indeed,
one of only a handful of American machines available to the general public at the onset of the 1950s.
Little information is available for this machine, I can however tell
you that it had a six inch Jensen loudspeaker fitted and used the following
five valves (tubes):
6SJ7 – Mic. pre-amp and AF amp
6SJ7 – AF amp
6J5 – Bias oscillator
6K6GT – Power output
6X5GT – Rectifier
Like most early recorders, there were three separate heads: erase, record and
playback, the technology for combining a record and playback head had
not yet been fully developed.
Seven inch reels were accommodated. Note the unusual tape path.
