Freed transformer was 18777, 100 watt rating 1650 Ohms on the primary

But more over a Quad of 300B's is generally considered to generate 45 watts or so I thought.

I had stumbled across this collection of circuits and had never seen any of them before. Last year I did a quad 300B amplifier using the Brook 12A circuit as the front end driver. It turned out to be a really nice amplifier. And it did about 40 watts clean. Again thanks for a great reply.
