EMI RS61 Electron Tube Microphone Preamplifier V72 U47

EBAY SELLER AUCTION DESCRIPTION

"This is for an EMI RS61 without a psu, in excellent working condition.

Possibly the best and most rare microphone preamplifier ever made on earth.

To the best of my knowledge no more than 30 units have been made,

please do your own search.
