Input Selector: A six-position switch for choice of inputs from:
 Tuner: Response, level. Sensitivity 80 mV. r.m.s.
 Records: Sensitivity 14 mV.
 There are four separate characteristics available, these being:-
   (a) Audio Engineering Society and RCA New Orthophonic.
   (b) Columbia (U.S.A.) LP and Decca (London) FFRR LP.
   (c) National Association of Radio & Television Broadcasters
      and H.M.V. (Angel) LP.

      Input resistance, 100kΩ .
Treble Control: Continuously variable from +9dB to-15dB  at 10 kHz.
Bass Control: Continuously variable from +12dB to +13dB at 40 Hz.
Volume Control and Switch: The switch controls the amplifier.
"From Tape Replay Amp.": This input jack accepts signals from a tape replay amplifier.
"To Tape Record Amp.": This jack permits the user to record on to tape from radio or   records when using a recorder embodying a low level recording amplifier.
The following components are mounted on the rear of the pre-amplifier:—
   (1) Co-axial plugs and sockets for tuner and pick-up connections.
   (2) Pre-set controls for adjustment of inputs from tuner and pick-ups.
   (3) A terminal strip to which a load resistor may be fitted for
