Marshal Power Amplifier Hi-Fi PCB Layout Only

This circuit is perfect for those of you who like to build Hi-Fi amplifiers that are solid and powerful. Marshal power amplifiers are known to have excellent quality for musical instruments such as guitars.

The output produced from this amplifier is 100 Watt maximum with a maximum 45 VDC power supply. Recommended power supply current of at least 5 Amperes. I apologize for not displaying the complete circuit. But here you can see a clear PCB layout and component layout, so if you want to make it just copy the image below.

Both the 2SC 5200 and 2SA 1943 final transistors will generate high heat while operating. Likewise with the transistor driver 2SC 4793, 2SA 1837 and BD139. These five transistors must be given adequate heatsinks so that the amplifier can work optimally.
