Technical Notes:
Meter Function:
This is set to give optimum bias at 65% reading. When
reading power 100% = both channels 2x 28W or one
channel 50%. All continuous at 1kH.
*RMS watts Based upon the RMS voltage output (V²/R).
Indicates the maximum continuous undistorted output
power.
*Push Pull is a very elegant way of 2 valves in
opposition, virtually cancelling out non linear distortion,
noise and hum. Whilst dramatically increasing the power
and damping factor. In Class AB about 1/4 of the output
is pure class A. Unlike transistor designs there is no
crossover distortion at any power of the Stereo 40.
*Ultralinear (or Distributed Load). This is a true "win-
win" output stage design. Having virtually the all the
characteristics and low distortion of pure Triode valves,
whilst keeping 90% of the power of pure Pentodes types.
