hey guys see if you can help me with this one........is there any way to check what is causing a fuse to blow? i know it was my preamp 12ax7 cuz i looked and it was split at the top.....but as far as the little chips and capacitors and whatnot go, is there any way to tell if you have blown those (burn marks, appearance, etc.)? also is it possible to fix this yourself? i have knowledge with a soldering gun and have worked with electronics but nothing as complicated as this. any help?
