A WORD OF ADVICE
about fuses – if a fuse blows it is
usually for a very good reason, it could be anything from a
voltage spike on the mains power, to a serious malfunction
of your amplifier. Fuses are there for your protection
treat them with respect, and never replace with the wrong
value!
WARNING! USE THE CORRECT REPLACEMENT
VALUE ONLY!
