Are you taking the voltage with the transformer loaded or unloaded?
The voltage will be higher when there is no load on the transformer.
you have to look at the percentage regulation, and whether you are measuring rms or peak voltage at the secondary. Are you measuring the voltage under load, or just by hooking up the transformer with nothing connected to the secondary?
I was contenplating building this or a Beta 22. I will be powering LCD3's with it. Has anyone done a comparison by any chance between the two amps. What is turning me toward the B22 more is the discrete design vs using opamps.
I finished everything but putting it in a chassis. I lost interest as I didn't keep any balanced dynamic headphones and had a bunch of other projects. I've recently grabbed some so I'll have to dig the boards back out and put them into a case. I've still got one to use that I had originally marked for the project.
