Realistic STA-20 Fuse replacement

Hello all -
I bought the receiver last year, have used it in multiple locations in my house with no issues. I moved it to a my sun room, plugged it in, then it blew the fuse. I replaced it with a 1.5A 250V fuse, multiple times. Each time I unplugged the power, replaced the fuse, plugged in the power then turned it on. Each time it blew the fuse.

I'm not sure what to do next. Any help is appreciated.

The most probable causes are shorted output transistors in the power amplifier stage, or shorted rectifiers in the main power supply.
