|One of my prize pieces of equipment is a pair of
Sony C-37A large capsule tube, condenser microphones. I bought these from the radio
station at college because they were getting hard to use, and an intermittent connector
problem resulted in a nasty high-voltage shock to the station manager! (He didn't
appreciate the benefits of old tube equipment!)
Click on the links below to view facsimile images of the manual
that came with my pair of microphones. The pages are dark purple
print on yellowed paper and look very much like old blueprints.
Note on page 6 of the manual where the original name (Tokyo Tsushin
Kogyo, Ltd.) was crossed out and replaced by "SONY CORP"
