My amp was damaged, PSU IGBT's & drivers were burned; at90pwm3b-16su also was damaged. I have ennough skills & expirience for repair this PSU, problem occured with pwm controller that I can't find anywere ( I understand that firmware is secret of manufacturer) , but maybe anybody have friends in companies that do service of Lacoustics amps... I hope that someone can help me, as I, in turn, help people with the service manual EV zlx. Edited by voron - 30 June 2018 at 12:45pm |

I think you should contact who ever is Russian distributor for Lacoustics and send the amp to their authorized service.

Local distributor can sell only whole PSU & its price is too much (1660 Euro)

The firmware has been recreated and optimized. Now PSU works fine after repair.

Hi Voron, I also had the same problem as you, one of my LA8s. I find myself in a bind following this PWM at90pwm3b-16su. Could you tell me how you went about programming this PWM? Thanks to you

Hi Voron, One of my LA8 at90pwm3b-16su is broken. Do you sell your firmware? What is the price? Thank you

I can sell preprogrammed MCU only. But there are some problems with delivery and money transfer, because I'm located in Russia. Where are you from?
