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

I don't think I have ever bought a piece of audio equipment from craigslist. What I ave learned from this thread?  Don't change this policy.

@2psyop I first found it on ebay. I cannot stand ebay's 15+% cut plus shipping. I realized it was close by, and as I am cheap, I searched for it on several sites and found it also posted on craigslist. But I admit craigslist is a hit or miss.

@parkergetdean it doesn’t matter what’s wrong with the amp. Anything other than a fuse you can’t go in there. Sell it as is or use it until it dies. Turn it on and leave on. 
 

Moving forward remember to tell yourself “I’m not rich enough to buy cheap”

Ebay, craiglist and facebook is where all the garbage lives. Sold by garbage collectors. 

thanks @audphile1. I don't think it was garbage though, there is always risk with used. I have long known that buying cheap is expensive but have not always made purchases accordingly.
