5000W is ridiculous for a home-made amplifier. It has no output protection.
It is very dangerous because its speakers are connected directly to the AC line voltage instead of using a normal isolated power supply.

It uses twenty expensive output transistors that might not be available anymore and they will get extremely hot without some kind of high-tech cooling (liquid nitrogen?).

Thanks for the reply.

MJ and MJL are currently available at around R35.00

That transformer can be substituted with an isolation type ( very large ).

The constructor probably fitted thermal cut out switches direct to the heatsink because yes that is very hard work to get rid of that much heat and quite a strenous task for those transisors working into a 2 ohm load :eek:

I think im gonna skip this one

I think the project is a joke.
You need only about 100W RMS per channel in your home to be very (extremely?) loud.
5kW is used at an outdoors rock concert. The people up close are deafened.
