Voltages underlined are peak signal voltages at 15 watts output. Williamson in new york by ed wallace in july 1953, high fidelity. The bias is set using active semiconductor current sinks.
The Williamson Amplifier Introduction Introduced By Wireless World In 1947 As Merely One Of A Series Of Amplifier Designs, The “ Williamson ” Has For Several Years Been Widely Accepted As The Standard Of Design And Performance Wherever Amplifiers And Sound Reproduction Are Discussed.
Williamson was an english engineer working for the m. Final schematic, as built design comments i would have preferred a valve rectifier. The schematic is as follows:
Williamson In New York By Ed Wallace In July 1953, High Fidelity.
It is certainly one of the most popular audio circuits ever developed for. It's quite alright to substitute the bias supply circuit from another amplifier in this volume or rearrange things (provided adequate bias voltage is available) in order to eliminate this part. Researching amplifier circuits on the internet.
Tube Rectifiers Have Internal Plate Resistance A Bit Too High For Williamson Circuits (But They Can Be Made To Work, Depending On The Amps Output Power Level Design And The Number Of Tube Rectifiers You Are Willing To Parallel).
The basic amplifier circuit should not be revised to include tone controls or. Voltages underlined are peak signal voltages at 15 watts output. Power output of audio amplifiers.
By This Stage, Williamson's Attention Had Turned To Loudspeakers, And Prototyping His Ferranti Tonearm And Pickup.
The proposed values for the components of the 6j5 amplifier are seen in the schematic below. His amplifier circuit design was first published in a series of articles in the magazine wireless world in 1947, and it immediately attracted a lot of attention. He later worked for the ferranti company.
