Description
Crown produced these excellent Tube/Valve preamplifiers to go with their 800 transports, from 1959-1964.
The various sections of this preamplifier include microphone preamps, playback amps, record preamplifier and record oscillator cathode follower output.
Over the years they produced 2 different versions. The most common version included front panel bass and treble controls with bias adjustment.
The second one (last 2 pics) was the broadcast version with rear adjust bias adjustments, Mic & balanced line inputs, front panel headphone jack and no bass or treble controls.
The audio signal tubes are 12AX7 x 2 and 12AT7 x 2 and the inputs of the RP 3 are quarter-inch headphone jacks which many users convert to RCA’s for modern use.
