I found a 2x12 Line Six Spider III amp for sale, the vendor claims that it can be fixed by installing fuses. Does this mean that the current fuses are blown, or that it never came with fuses? In the former case, how would I be able to tell if the fuses are blown, or if it only needs new fuses and there's not some other underlying issue?
If a 25 cent fuse was all it needed the seller would have already replaced themthink about it. I would run awayfast.
If the amp works there is not any reason to change the fuse. merely placed the previous one lower back in. The time to alter a fuse is whilst it blows. using the incorrect type of fuse ought to enable your amp to be broken interior the form of a ability surge, and/or ought to create an electric probability. do no longer attempt to artwork on something interior the amp. Amps are risky. some varieties are even risky whilst unplugged. Fuses do no longer influence the tone; sounds like placebo result (on you, no longer the amp).
well if the fuses are blown it probably wont work. when a fuse is blown you can see the metal is broken in two pieces inside. here's a picture. askthemechanic .uk/electric this may not be the right kind of fuse but the idea is basically the same.
Ripley, the Line 6 tube amplifiers can have both externally-accessible and internal fuses. A fuse can blow from a voltage spike, or from malfunctioning internal components; it is there to protect circuitry from further damage. Merely replacing a fuse without understanding the underlying causes for failure is just a temporary solution, which at best may only delay the need for further repairs or replacements. If you are really interested in the amplifier, see if the seller will let you take it to a dealer for evaluation. For a modest cost, you will get the complete answer, and maybe save yourself some heartache. Best regards, Dana
