Williamson Amplifier - Modified


New Member
Dec 12, 2022
Hi there,

I am an electrician, so please forgive my ignorance on some of the finer details of tube electronics.

I have been in the on and off stage of trying to start my build of a Williamson amplifier, using 2 807s on each side of the push-pull cycle.

But I seem to remember 10k plate to plate, but because I am going 2 in parallel, im remembering 5k plate to plate impedance.

So this would create about a 50Watt maximum amplifier per channel, but what rating of output transformer (p-p) would I aim for?

Thanking in advance.
