Great 100W+100W Power Amplifier (LJM MX50)

For a Band practice or for a special occasion, we need a more powerful amplifier. For this purpose best and cheap amps are Chinese DIY kits.

They work great and sounds like a original amplifier.

Actually i made a good amp using a LJM MX50 DIY kit i got from e-Bay.
It cost me only 30 dollars with the shipping charges.

Actually it comes with 2 mono boards. using 2 separate transformers and power supply units to 2 boards will give you a best quality amp.

I used two 28 volt 3 A transformers. 28 volt transformer gives about 36 V when it's converted to DC.

7"*4" heat sink will be enough with a 3" computer fan.

Its powerful enough to drive a 500 W column in its maximum sound.If you drive it with the computer or a sound mixer, you do not need a pre-amplifier.
