Hi,
for startup sequence, yes, is possible unbalanced but think it's catastrophic for audio (the frequency varies continuously with the load). apart from the imbalance
in the case of dual output.

TL494 is good, Also you can add a driver eg. IR21xx or a transformer to drive the mosfet.

however I've solved the problem at the start of 21531. in the presence of a short circuit or high absorption. I enclose a pic just for curiosity. worked from 2002 until 2007 without problem in class H amps.
I think it works better, less RFI / EMI of some unregulated on the market.
somewhere in this forum I already put the diagram.
Hi
Where is a diagram not to wander?
thanks and cheers !

Hi,
I not have time for put new, maybe at weekend.
I do not remember where thread I put it, sorry.
If you are interested, I have some pcb (equal to the photo), I think 5-6 pz.
components can be found easily (few components).
I have the PCB and transformer to + /-68v 14Amp, and mosfets.
PCB, MOSFET and small heatsink for 5 pz, I can give.

Regards
Roberto
