[Drake] EV mike?

[Harvey Hetland]

Steve:

Drake sold their model 729SRD microphone as an accessory for the T-4XB.
According to a sales brochure from the early 1970s it is described as a,
"Drake-modified EV 729SR for VOX or PTT with Drake Xmtrs.  Hi-Z Ceramic
Mike.  Highly directional.  Dimen: 8-1/4" x 4" W x 4-1/4" D.  Wt. 1lb.,
incl. cable."  The list price was $17.00.  The 4 inch width is due to
the base in which the microphone sat.  The Drake HF transmitters were
high impedance microphone inputs (50 kilohms nominal), although low
impedance with the TR-7 was provided via a separate pin input.  A
scanned image of that portion of the sales brochure can be viewed at:

portion of the brochure is a description of the MS-4 speaker cabinet.
