very good James....I like things that are adapted and then made better....

I started with this design..........................
http://tube-amps.net/How_Hashimoto_sounds.htm

but couldn't get it to sound as I wanted it to so ended up changing quite a bit.
I didn't like what C3 did to the sound so omitted it. I have to say it will not please the SET Purists as I have used Feedback permanently, not in a variable way as Mr. Matsunami did. I am afraid I am of the school that has nothing against Feedback. The few tests I have done on SET's I have always felt it is the sound of the Output Transformer that the Purists must be liking. The Valve (SET) itself often has a ruler flat frequency response if measured at the Anode but by the time it has gone through the O/P TX it becomes ''an SET''. Let Feedback do its job and you hear what the Valve can do, in my humble opinion.
To compensate for the loss of Gain due to the Feedback I added another stage, outside the feedback loop actually, which also made the whole thing non-inverting too which bothered me slightly perhaps unnecessarily so but it did!

Thanks James, always interesting to get a bit of the thinking behind DIY projects. Curious as to your preferred sources for specialist transformers, both o/p and mains.

.................................Curious as to your preferred sources for specialist transformers, both o/p and mains.

I bought the Mains Transformer with the part built box so I'm afraid I cannot help you out there. I have used VVT in the past for Mains and Output and would have done again this time for the Output TX's but got no reply from them so I approached Majestic Transformers......

who were unbelievably helpful and friendly. I gave them as many of my specifications for the TX, Current, Power Output, Impedance and size etc etc and they came back with an acceptable quote. I have to say they do perform extremely well.
Thanks for the interest,
James.
