I need to replace the fuse that runs the 12volt 35 amp section of my bommer / Palomar elete 500 amplifier. The fuse looks as if its never been changed and is old and difficult to read. I think it's a 25 amp (old glass type). Can someone tell me what fuse I should purchase ? It's the fuse that runs the power supply section only. There are two other fuses located inside The amp, not sure what those are but there not blown out but difficult to remove. Since there good im gonna leave them in there.
