Sony C-107
A Sony condenser that turns up in the background of a 1979 roundup of vintage studio gear - and almost nowhere else.
Overview
The C-107 is one of those Sony microphones that survives mostly as a footnote. The clearest period sighting comes from a vintage-gear survey in Recording-Engineer (June 1979, p.95), where a photo caption identifies a C-107 as an early-1960s Sony condenser, grouped with a C-220A from the same era and a run of other studio classics. That caption is essentially the whole documented story: a Sony condenser from the early 1960s, photographed alongside the mics that defined the period.
There is no confirmed production run, no published price, no capsule description and no frequency-response figure. There is no owner consensus on how it sounds or what it's worth today. Collectors know the C-107 as a name on a Sony chronology, not a mic with a cult following. It's the kind of thing that surfaces in a studio's back cabinet or an estate lot, not on a wish list. Treat every listing claim as unverified until the capsule and electronics can be inspected.
Sony's early condenser line is respected. A 1992 Studio-Sound chronology (February 1992, p.49) tracks the C-37A and C-55P as working studio staples, and the same piece notes the later C-800 was positioned as a successor to the C-37A. The C-107 sits in that early-1960s window but has not attracted the same documentation or demand. It's a real Sony condenser with a thin paper trail, best approached as a restoration project with unknown upside.
