Above is your user manual below is a service and repair manual.
Indeed i would suspect something around your Final Output semiconductors, and any associated resistors?
You really must obtain a service manual, here there are the troubleshooting steps required to isolate and hopefully allow repair of your unit.
Look for any discolored components etc, check if any are overly hot... use a temperature probe on suspected components. Freeze spray may also be useful in diagnosis.
Use your eyes & nose to isolate the bad burnt overheated components, I sometimes use a straw up a nostril and selectively go over suspect parts, and "Sniff" to try and detect the overheated smell... it works.
Above is your tech support link, contact them for any info you require.

This is a common problem with Bugera. And, unfortunately they are made by Behringer who is known to have the worst customer service of all and do not follow through on their warranties.

Zoom MRS 1608 will not power on
I suggest checking to make sure those 2 units can actually use the same adapter and also check the polarity on both to see if they are the same. Most stompbox stuff usually has negative on the center of the socket, instead of positive like other devices. If I spend a little time I could find the manuals and find out for myself but, this was my logical "top of my mind" kind of advice. Those values (volts,mA, and polarity) must be known in order to help you further. I believe it will be 9v, a few 100 mA's, and negative in the center on both but, not sure.

Baldwin pianovelle ps2500 my piano turns on but speakers don't sound can someone give a hint to solve this problem
So I got a used one of these for free because it had the same issue.
I read about battery failure, so I opened up the piano and sure enough the battery had corroded. I also read that the battery is only necessary for the memory feature, which I don’t care too much about. I pulled out the board (super easy to do, no screws or anything, it just pops out) and took it a local electronics/tv repair guy. In about a half hour he took off the battery, fixed a bad trace on the board with a quick solder, and handed it back. $40.
Plugged it back in, bam works like a charm.
As long as there wasn’t too much damage from corrosion, a repair guy should easily be able to do what I described.
I hope this solves your (and anyone else’s) problem!
