AKG C24 Stereo Vacuum
Tube (valve) microphone evaluation.
Tested 5 April 2007by Eddie Ciletti
Comparison of t two "identical" mics of
different vintage and capsules.
Great River transformerless mic preamp
to Sony PCM-R500 RDAT. Please note that of the two C24s, the upper
(brass CK-12) mic-to-power supply connection was a new 35-foot Mogami
cable while the lower (nylon CK-12) cable was a vintage 70-foot cable.
I will do another test with the cables reversed.
