Roland PM 10 monitor no sound

Spare parts for Roland PM10 personal monitor.
I’ve dug my old amp out of my garage to see if I could get it working. After having a look under the hood, I’ve found this part to be burnt out. Can anybody advise on a new spare part. Tried to google the item number to no avail.

your transformer is not burnt out. check your fuses. if that doesn’t work Take the unit to a Roland service center, or they may be able to direct you to a closer tech.
