Testing Electro-Voice 664 variable D moving coil microphone with Pleiades 2 k117 preamplifier old version

At your risk. The older 2 k117 version has a lower load resistor on first stage than 100K, no potentiometr between the 2 stages, a lower load resistor on second stage, so gain is lower. The mic tested is new old stock bought from Yiannis who supplied these in the 60's to the military television. At that time the goverrment in Greece was miliotary so was the TV station. From the mics tested they liked most the 664. The particular mic not sold to them is s/n 164995. After a new flexible Eurocable of blue color was soldered to the Amphenol connector at the low impedance terminals, the mic sings, amazing sound and detail. Tested at singing male voice 24in from nose, about 30 degrees towards head from above.
