Hi all
I like to make Class D Amp with TL494 but i can't find a tested schematic
i attach a schematic but it works with single voltage
i need 500 (4R) watt and i don't think single voltage can work better in this power.

some schematics of this amps have not Gate,i don't like to use any not gate


Is everyOne have TL494 Tested amp sch?
please help

Well, you sound childish.
If you don´t "like" the Technically correct answers you get, what can we do?

As TL494 have easy circuit,i use it.
do you know better than 494?(i just need a 400w on 4R)
i made TL074 Class D Amp but it not work.
i run 494 class d amp but +peak's fet get warmer.
and output sound is very bad.
You just proved my point ;)
 
You're right and i respect your comments too but i can't find a original irs2092.
this is my problem.
i like to make this amp with OPAmp and 555 oscillator.
like attached file.
how is this?
