PRESTO developed many tape recorders and players, and was about a year behind the development of similar models comparable to AMPEX.
Since product research and development stoped about the time of the sale of the company, only a few stereo models were made.  Their various tape recorders were of exceptional value.  Many special models were manufactured for MUZAK,  the government and military forces.

PRESTO made many special tape recorders.  The unit to the left was made expressly for MUSAK, for their "elevator" music playback systems.  The unit to the right is a Military spec tape recorder made especially for the armed forces.  Although the manual is dated 1957, supplements dated 1973 included with the manual leaves a little confusion as to when this model was actually made.  It must have been closer to 1957 than 1973.  It had never been placed in service, is cosmetically and electronically as a new machine.  It has 3 speeds, is 1/2 track mono., and solonoid operated. It has heavy duty components, built to military specs.  PRESTO also made special small tape players for airlines, passenger boats, and the Railroad.

The Model 825 Presto stereo tape recorder.  This was the 800 series, available in Mono, 2, 3, and 4 track stereo configurations.  1/2 and/or 1/4 tape.
This was introduced in 1957, and was priced at $3150 for the console model.  It had individual head tape lifters, and seperate power supplies for the
record/bias circuits.
