Modifications:

This is an amplifier that deserves updating, it can be very rewarding to get the most out of it.
There are some parts that are rather small designed, and performance can improve when these parts are exchanged for
better parts. It is possible to improve the output power up to 28 Watts RMS p/ch at 8 Ohms.
Also the overall damping factor can be improved. This map has NO protection circuit: add a simple one.
