Additional Details


The PT7A was a professional, three-head twin-track mono recorder available in  rack, case or console. It appears to have been a short-lived interim model between the P6 and the PT-60 as there is no mention of it in any trade magazines or directories, only in a 1954 Magnecord catalogue.
Reel capacity was 10½ inches and tape speeds were 7½ and 15 ips. Speed change was electrical and start/stop was almost instantaneous (0.1 seconds)
Tape lifters were used to  lift tape from heads when rewinding or fast forwarding.
The heads were triple-shielded to reduce cross-talk and hum, and could be removed or aligned separately
Control of transport functions (forward, stop, rewind & hi-speed) was by means of interlocked pushbuttons and could be controlled remotely.
