AMPEX 350 Tape Recorder
Message Board - AMPEX Model 350 General Discussion
The Ampex Model 350 magnetic tape recorder is a two-speed audio recorder designed for use with standard ¼ inch tape. The Model 350 is available in console, two-case portable, and rack-mount styles, all with either full or half track heads.
Independent record and playback systems allow the tape to be monitored while recording. A phone jack is provided to monitor either the record input signal before or during recording, or the output signal from the playback head while recording or during playback. An A-B switch is incorporated in order that direct comparison can be made between the original program and the recorded program. The same switch transfers a 4 inch VU meter for level comparison and monitoring. The
VU Meter is also used to read bias and erase current.
1953 was quite a year with projects started in 1952. As
mentioned earlier, Ampex was having production problems
with the Model 400. Frank Lennert, although he was head of
manufacturing, decided to do some engineering on his own.
One weekend, he took the reel motor assemblies from the
Model 300 and the capstan, head assembly and electronics
from the Model 400 and machined a new top plate. He had Jay
McKnight handle the electronic details. They then put it all
together, and this recorder became the Model 350 of which
more than 6,000 were sold. It is a proud Ampex success story.
