amp I bought 3 days ago not powering on - electrical engineer advice wanted

@devinplombier I want to learn to fix it myself but I know my limits. If I learn to fix things I should do it on gear that has little value. 

There are a few techs I know in a 20 mile radius, one of them is good but they had never done a thing under $300. So I have 300 reasons to open it and at least scratch my head. 

@parkergetdean 

Yes, get a dead audio component off craigslist for 10 or 15 bucks and fix it. That'll get your feet wet, but - if you're successful on your first try, there's no turning back and you'll have a new hobby :)

Keep us posted!

Looking at a schematic of the A300 and assuming the A308 is similar, the problem appears to be a bad thermistor downstream of the power switch. It is a $3 dollar part (Vishay SG27) and should require no more than a 1/2-hour of labor to replace.

Wow! Thank you @gs5556 that’s very precise!

@devinplombier I have a few busted amps, good enough to practice
