I had the blinking power light happen to me on my Hafler DH 500 today. Googling turned out to be at that it's the thermal sensors need replacement. i might as well fit a new fan in there while i'm at it.
Only problem is I don't know which parts those are?

Additionally I found this out when deciding i should probably check the amp's DC output. Is this one trim knob the only one I need to use to fix that? Not sure how to do if if I have an older revision that didn't just have a single pot to change that. DC offset adjustment on a Hafler DH-500? | Audiokarma Home Audio Stereo Discussion Forums
I have a multimeter but if someone could give me a total dummies guide on checking my DC offset I'd really appreciate it. In the meantime I am trying to find what part I need to replace that thermal sensor.
