This is a 1945-49 #HMV model 2350E. This was the amplifier used for field recording 78’s. It has special bass boost and treble cut knobs depending wether you are recording from microphone or reel. Very few of these were made worldwide, and if you have any kind of #recordlathe or #presto or #recocut this is the vital ingredient in making your #78rpm #records cut with proper #sonicrange.
