See the fender field guide A discussion of the williamson amplifier should be first preceded by an overview of its context in the evolution of the vacuum tube and its application to high fidelity audio reproduction.

The thd of the amplifier has been measure at 0.75% thd at full power and less than 0.25% at 1w. Primary load impedance = 10,000 ohms centre tapped.

If you see a problem with any of the schematics, please email me so i. Over the years there have been quite a few variations using different tubes and different biasing of the original tubes, but having built many williamson amps 20 or 30 years ago, my opinion is that there are now better topologies to drive a pp pair of output tubes.

Williamson during world war ii.the original circuit, published in 1947 and addressed to the worldwide do it yourself community, set the standard of high fidelity sound reproduction and served a benchmark or reference amplifier design throughout the 1950s.

Thanks to preservation sound for everything they do and are, as they are the ones i took the above image from. I have built the amplifier with the values specified in the schematic ( but i have a power transformer that is rated 230vac to 200v, and the grid voltage is up to 238vin my neighborhood.

The bias is set using active semiconductor current sinks.
