Description
This is the most simple and cheap design of 150 watts power amplifier you find on different sites.
It uses a combination of darlington pairs which are TIP147 and TIP 142 as power transistors.
This amplifier can work fine with 30-0-30 DC supply rating but it gives lower wattage with this supply where as you can obtain almost 200Watts peak power if supply rating is 45-0-45 DC and with 4 amperes. You can obtain this rating from 32-0-32 center tap transformer .
