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

@parkergetdean 

Probably be a good idea to get a backup battery since you know it is going to fail! Can't even guarantee there will be any left in five years or so..

If your tech told you what he paid, that is a good sign! Not a bad time to tell him it may not have been serviced in some time and a cleaning/lubrication may be in order. 

If it's already on the bench, he may do it for $100 or less...and it may sound better because of it.

@thecarpathian 

See? 28 days later, we now know exactly what model he has. Is that important?

Oh, for goodness sake!

If they were having a ’Mr. Ineptitude’ contest, no one else would even enter!

They’d go; "He's ​​entering? Forget it."

At least it's not an Airbus A300.

Oh, wait...
