That is the schematic for the M7 audionote clone. His runs 360v ct. We need some advice on this. I am competant to build from an existing schematic with voltage test points, but I don't yet trust my design or substitution abilities. If you can find one an old dyna would work according to my calculations, and that should be cheap. To be truthfull; crunching the numbers still comes out to about 125$. Thats 60$ for the trans. 20$ for the chassis. 10$ for tubes and sockets 30$ for chokes and Well I geuss another 25$ for parts, although I have a lot in my junk drawer. What do you have for figures?
