This is overcurrent protect for HF driver, can be set with change 0,47R.

This protect don't compress peaks.

It just clips them. Won't that 10 watt resistor go smoke if you run the thing continuously in protect? DJs have been known to do that. I'd beef it up to a pair of 20 watters in parallel - and don't forget to heat sink the power transistor.

Yes resistor must be 40W if power is continuously double than maximum (25V RMS on driver), I forget protect from DJs

Protect with MOSFET instead BJT.

Sir Apex,
Can we cover open front of the box shown in post #77 with some metal gril or mesh ? does this will effect the performance ?
