Hi all,
I have just built a lm3875 audiosector kit using a dual 25v 300va transformer. Everything is working fine, but i am worried that 36vdc is too much. They get very hot even using a AMD 2000Mhz heatsink!
Is this too much, and what would be the best way to reduce the voltage on this pcb kit?
Many thanks
Ian
