Which Fets are T1 and T2 and can I put for example 2 X IRFP460 into your design and bring up the supply to 150V?

Thanks for looking at my questions.

IR2117 is only one side driver.IR2184 is two side drivers with internal dead time,so my ansver is not.But it can be used with different schematic.
R can be 3k9 2W
Transistor can be darlington for twice voltage than supply,and 3A min.It's better to use external psu,but not more than 15V! Over it IR2184 blow up.
If use transformer it must have voltage on secondary 9-10V.
Yes,you can but look out for high current lines!

also can i redraw your schema and use ir2110 or ir2153 as the gate drivers.?

thanking you in advance steve .
First sory for late answer,there's no new mail from this forum and I dont think about this.
Tried with +-40 on 0.5R load,which is same.lights in my house blinks with music
Fets should use with smallest gate charge what you find.
I dont know can be IR2153 used for this.
IR2110 can be used,but one input must be 180' out of phase than other.

THERE'S MISTAKE ON PCB!
Pin1 and pin2 on SG3525 must been swaped.Pin 1 goes to pin 2 on pcb and pin 2 goes to pin 1 on pcb.

Ok,here's it.You can use inverter IC instead of transistor.I ask my friend can be ir2153 used for this.
