Complete Amplifier Project

In an article I shared an old amp circuit (Mosfet Amplifier 150W) project, more advanced, I applied again with additional circuitry Circuit 4Ω 8Ω speaker with a 100w power 150w with hoprarl able sooner.

Amplifier circuit diagram and PCBs;

Preamplifier circuit

Pre amplifier circuit works fine, I’ve enjoyed it. In addition to the magnetic microphone input with each instrument (guitar, electro-binding, etc.) by connecting guitars, etc. You can use the amp is not very efficient, but can not get the guitar amp for the new starting time will take

Power supply circuit

Amplifier power supply circuit I used as a standard symmetric. Preamplifier supply circuit for use again at a standard symmetric but to obtain a more stable DC voltage of the voltage regulating integrated I used. Standard supply circuit diagram that I did not need to draw direct printed circuit board supply circuit diagram so I do not have just printed circuit board. I use the amp with separate power transformers Preamf. Preamf the supply transformer is small print you will see in the pictures I put on the card.
