One of these silicon amplifiers that cought my eye and that also seems to be of a pretty good quality. There was a very good Swedish designed 75W amplifier once. It was said to be VERY nice but the backside wwas that it was very unstable. Once it started to behave badly, it selfdestructed in picoseconds. I see no indications that SymAsym is like that.
I did purchase all components for a complete stereoamp as I also happened to find a pair of suitable transformers. The "problem"is that I have a pair of Chinese DIY amps that also wants to use the same trannies.
An hour ago I ordered boards for the SymAsym. Had boards made but no holes drilled and I have NO patience to fix that.
