Gimpus Stereophilus!
Audio Fidelity (the original AF company) was founded in the early 1950's by a chap named Sidney Frey. His firm along with Westrex collaborated 45/45 single groove Stereo LP discs in November, 1957 and made Stereo viable for the mass public. His recordings were generally excellent technically. Musically they are a mixed bag. I am fond of the Dukes Of Dixieland and Al Hirt recordings and Louis Armstrong recordings. He first issued 2 track tapes at 7 1/2 IPS and then later released 7 1/2 IPS 4 track tapes of superb quality. A note in general about pre-recorded reel tapes. The pre-1966 tapes were duplicated at 4 X speeds. Later tapes were also commonly duplicated at 8 and 16 X speeds and often at 3 3/4 IPS speed reducing their quality. Most rock tapes were duped at the higher speeds though many of the late issues outside of record clubs were still very good.
but some not so. I don't know if they are bad from being abused or just bad recordings. I don't have any 3 3/4 ips as I'm not fond of the sound quality.
