So yesterday I was playing through my Windsor and I just lost sound, I could hear it fade out quickly, as if I had just switched it to standby. The power light also went out. So I thought maybe I lost power, but I didn't, the power tubes were still lit. I checked the fuse, it wasn't blown. I tried it turning it on again later, and the power light still doesn't come on, but the power tubes are lighting up like normal. Does anyone have any idea what this could be? I'm hoping it's just something that came loose that I can fix myself, but if it's anything complicated I guess I'll have to take it to a shop. Any help would be appreciated.
