For the first try, this made me quite happy. I'm not sure how good it really is, but I guess in some time I'll need to find a quality audio test equipment. So far, I'm only having fun building it.
All this time, I was powering my amp using +/-30V/5A Rigol power supply. Obviously, this is not something permanent, and I'd need to build a separate power supply. Since I'm striving for the Hiest of Fies, switching mode supplies are out of the question. This means a big ass transformer.
Previously, I have calculated that I need 120VA source power, but then I thought to myself, why? Yeah, the idea was to build a high power amp. But, let's be honest, I will probably never use it. During the sound test, I found out that even a couple of Watts is already to loud for my delicate ears, and 100W capable speakers are heavy and expensive, I decided to lower down my power expectations. How much? As much as my easily obtained trafo can give :)
So, in my company's scrap room, I got nice toroidal, bipolar 19.5V/2.6A transformer, perfect for my project. This translates to 101.4VA output power, and with the efficiency of 66%, I can expect some 66W output power. Not bad for saving an effort of buying an expensive trafo. And with a notion, that design is easily applicable for higher supply voltages, if I ever find a more powerful trafo. Anyways, I dug out some bridge rectifiers and thick elkos, and contrapted myself a lovely little full-wave rectifier. I was lucky to find some 4500uF caps, so power demands should be satisfied.
