I have an old Rotel RB-991 that just recently stopped working. I thought maybe it was the fuses so I replaced them, now I am getting smoke (briefly- obviously I unplug it quickly when it starts). I can imagine this thing is toast- but does anyone have any idea what would cause this? I did opt for a 10 amp vs the 12 amp- would this have made this happen? Anyone know where to search for Rotel replacement fuses? Thx
