Congratulations to Russell Medcraft who not only knew the correct
answer but supplied the Hound with a fascinating piece of information on lasts week’s Mystery Object of the Week!
For Hound followers who may have missed Russell’s original answer read below:
“Alfred Clark was the first EMI Chairman. He had worked with Eldridge Johnson on an improved soundbox design which they patented. On this EMI subject, I helped P.D.R..Marks develop the famous EMI 806 Microphone amplifier and other associated equipment whilst I was in the EMI Studio Sound laboratory during 1958 and 1959.”
