Dear Mr Pass,
I really appreciate that you shared this amplifier design,I have built the SOZ with 10w output four years ago.Right now,I am looking for your new amplifier.I guess this one is the best choice. I have two idea to modify this amplifier.I expect you can take a few of you time have a review and give your suggestion.

1. May we use a single-end output transformer to replace the R2 and remove the output capacitor?If we can change this,what primary impedance of the output transformer should be the best to match this amplifier? Not sure whether impact the amplifier performance?

2. May I use the SJEP120R100 to replace the power MOSFET?I guess the distortion will be reduced.

I am expecting your reply.You help will be great appreciated.

Regards.
Leo

There is an article in Linear Audio Volume One which deals exactly with the questions you have posted. There is a schematic and everything.

Hi i am living in australia and im quite keen to build the amp in this article-is there anything that needs to be changed in the design to run on 240 volts AC and how many watts rms does it end up putting out? Im very new at building this sort of thing so any advice would be appreciated

Isn't grounding the output (to protect the speaker) a short-circuit?
Why is it different in this case? Thanks. Vince

I build, therefore I am.
