HiIt seem to be a bad very amp plans, here's a email I received about it;

Hi Gaetan
A good amplifier will include one or more of the following attributes;
- A stable constant current fed input stage.
- Well thought out gain stages (2nd and 3rd stages)
- Well thought out component choices for low noise, speed, reliability etc.
- A degree of symmetry so that the positive going signal is treated in a similar manner to the negative going signal.
- A clear and logically drawn schematic
- A clear and logically defined physical layoutThis amplifier does NOT display any of these. I have seen this schematic around the internet for a long time now. Why anyone would bother to build it is beyond me. It would be cheap to make of course, but that saving will be lost very quickly when it fails and takes out more than you bargained for.
Cheers & Good Luck
