Howdy,
So I just finished assembling the PCB for this and I am happy to report it does power on and behave like an amplifier. However out of the gates I have found Q13 and Q11 get a bit toasty after a minute or 2, and I am not sure what is going on with my power supply. But with this board when I crank up the volume a little bit. The LLC converter has a spaz and the amp goes into protect. I have an 8 ohm 6 inch driver as a dummy load while I do low power tests, but can't seem to go past 10 watts without something going oh sorry mate the bottom half of the heatsink just fell off and now theres aluminium shrowd everywhere. When I do a power cycle everything is back to normal which makes things harder as I am then not sure if its a short from instability or something. Appart from that when in the "Fault" condition the LLC converter makes a horrific sound then shuts off.
