• Notes

• Wireless World Quality Amplifiers

  4-, 8- & 12-watt versions.

  This is the second version of the Wireless World Quality Amplifier described by Walter Cocking (1907-1984) in Wireless World in May 1934.
  Here he described 4-, 8- & 12-watt versions, using suitable output transformers and valves. See parts list.
  This circuit was similar to the 1934 version but used a common un-bypassed cathode bias resistor on the first push-pull stage.

  D. T. N. Williamson based his design on the 1934 & 1946 Walter Cocking circuits
