Upgrade of TDA2005 Amplifier

This is not so complicated Amplifier that could be use in household or in the cottage or anywhere where you think off.
This is upgraded version of my first instructable “Amplifier TDA2005” . Basically this small amplifier was originally created like low cost solution for my cottage near the Danube, but after connecting it with some old HiFi speakers i decide to keep it and with some improvements use it as good audio systems. Probably the old audiophile will say that something that is based on TDA2005 cannot be consider audio system, but after lots of hours spended listening to this small beast I am pretty pleased with the quality.
My personal opinion is that good audio system is the system that you could listen for hours and that the sound is not irritating for you, for example during the nap.”
