Hi everybody, I'm repairing my AG500SC head, which had a burned cemented resistor. As I'm reassembling it, I'm ashamed to admit that I hadn't noticed a connector could go in two places... You can see that on the photo here , it's right next to the input jack. I've been searching, but I haven't managed to find any good matching photos of that on google to see where that cable goes... Would anybody be willing to just get the top off of theirs and look close to the input jack where this thing should be connected ? It's a couple screws and the top goes off I swear, don't have to do anything weird to the amp to see it... It would mean a lot, thanks in advance for your kind help !
