I wouldn't let that theoretically designed amp anywhere near my loudspeakers!
Where is the protection circuit that stops high transients and DC going the speakers. The 1N4007 diodes will not stop serious back EMF.
greetings 1000 watt simple PA amplifier can it be used in 2 ohms at 110 dc
supply rails what would the power be with MJL21195 MJL21196 with same supply just finished another similar PA amp with 110 volt dc supply rails
I guess this amplifier will be *hugely* popular with noobs, because it has the irresistible combination of the magic "1000W" label and "20 output transistors", but it will be a nightmare to dissipate all those watts wasted as heat.
I suggest you build this much more advanced project instead;
With 1r0 emitter resistors on the outputs, the output bias will be approximately 26mA for optimum ClassAB........... but it will be a nightmare to dissipate all those watts wasted as heat...........
With 1r0 emitter resistors on the outputs, the output bias will be approximately 26mA for optimum ClassAB.
This gives an output stage dissipation of ~51W for all 18 devices. Add another 6W for the drivers. Quite manageable, especially for a "big" amplifier that will probably be fan cooled.
