Hello,

I found this amplifier in a dumpster (Rotel rx400L). There are two 4amp fuses in it that have blown a couple of times now, after I replaced them.
Since both of them keep blowing simultaneously, I assume there's a short circuit in the transformer, and not that for example transistors in both channels are broken.

I'm a novice, and I wonder if anyone has any suggestions about what I can do to make the amplifier work again?
