hi to all!!! at first when i build the amp ,the IR2110 was FAKE! i bought 2 off them both FAKE! after i bought the third IR2110 the amp came to life.....the sound is just amazing...very clear ...i use IRFP260 they are cold ....the output coil is hot..i use a toroid from an old pc power supply ....but even with that the amp works very well and sunds great...(sorry for my english)

hi dear
what voltage rails are you using
thanking you
He uses +/- 28Vdc for the moment for tests.
After all is tweaked and the SMPS is ready we will connect it at +/- 95Vdc.

do you have any idea how to add effectice short circuit and overcurrent protection..?
I think this is important thing
Just to give you some ideas... Using a 555 monostable, some transistors (or perhaps, a plan comparator, you can easily use the shutdown input of the IR211x to implement an overcurrent/short circuit protection protection
can you offer schematic ?
its new for me ....
