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


I bought a used Musical Fidelity A380 in good condition. Played it every day, worked fine. 

Today it did not turn on. There were no sign of failure yesterday. Could it be a fuse or power supply?

it turns on now 4 out of 5 times. 

maybe it was something behind the button. 

But your question prompted me to text my repair guy and have it checked out. The remote only works 50% of the time, maybe that can be fixed as well. 

So on mine for the volumn it did not work the volumn so like tha cat and curious i took the top off.there is a motor and gear .I cleaned it with compressed air then deposit electronic cleaner put very light oil droplet through a syringe needle and it works. Save myself some money and exercise. Happy listening.of course make sure you unplug it and wait for caps to discharge.

Whatever you do, once you get it sorted, solid state equipment should be not be turned off.  This practice minimizes stress on the inyernal components and likely allows the unit to last longer.  Turn it on and leave on.
