Shure M60 (c. 1967)
Little is documented about the Shure M60. The record that survives is essentially one short item in Audio (May 1967, p.77). It described the M60 as a general-purpose, non-equalized vacuum tube stereo line preamplifier. It gave extra gain for magnetic phono cartridges, microphones, and tape recorder outputs. A hi-fi dealer or serious listener might have used it to boost a weak signal before the main preamp.
The specs listed at the time were modest and specific:
- Gain: 17 dB (7:1), with 35 mV output for a 5 mV input
- Circuit-change information supplied for one-third and two-thirds output levels
- Vacuum tube, non-equalized, general-purpose design
Don't confuse the M60 preamp with the Shure SM60. That one is a separate late-1960s omnidirectional dynamic microphone that Shure advertised heavily for studio and field use. Different products, different model numbers - the archives sometimes blur them.
Beyond the 1967 Audio write-up, the M60's history is quiet. It appears to have been a utility product rather than a headline item, and surviving documentation is thin.
