Hello! I am new to the forum and had a question that I can’t seem to find an answer to searching forums. I have a vox ac15c1 that occasionally stops working, no tube glow at all. When it first happened I checked all the fuses (out of the amp with a multimeter, all checked out) and after I put the last one in again (ht one) and tried the amp again, it worked perfectly again. The second time I just took out the ht fuse again, squished the fuse prongs together some, plopped it back in, and worked again. Happened twice today again, same solution l. Pushed with a popsicle stick near and around the fuse to see if there was maybe a bad solder and couldn’t get the amp to repeat the behavior. Does anyone have an idea? Could the fuse be failing but not all the way yet? No other issues. Before I take it to a tech figured I’d see if your collective wisdom had encountered the issue before.
