Here is a small amplifier using the fine Electra-Print PSA-2N phase splitter autoformer. It is good for 7 watts and will do excellent for biamping. You will find that the autoformer works very well and gives very nice sound. The Electra-Print output transformer has a very wide flat bandwidth. This is a great project for a beginner builder because there are no adjustments to be made. All designs are the sole property of Electra-Print Audio Company with all rights reserved worldwide.
