In this video:
The customer has a Phonic Max 250 2-Channel amplifier in need of repair. The condition presented was "no power (pwr) will not turn on". After verifying the no pwr condition on my test bench I took apart the device and found a bit of carnage, exploded capacitors and other burned or failed components. Needless to say, there was a bit more to troubleshoot than the power supply. I will put a copy of the manual and schematics I found on my google site (link a little further down).
