Maintenance:
Leave it on or turn it off:
The product is designed to be left on all the time. The
exception to this might be a case where the preamp will not be used for an extended
time - in that case it can be turn off. The main power switch is located next to the AC
power cord.
Cleaning:
The fi nish can be damaged by harsh cleaners and abrasive cloths. We
fi nd a damp soft cloth works best. You can also use a mild solution of windex or white
vinegar.
Replacing the fuse:
The fuse should only be replace with the same type and size as
indicated on the rear. Audio Specialty FUSE: NOTE: The “Overload” and “Time Delay
characteristics” will differ slightly (due to the different metallurgy of the fuse elements)
between commercial grade and audio grade fuses. We can’t guarantee that
your audiophile grade fuse, won’t blow at a different in-rush current threshold, than
your stock commercial fuse. Use of other than approved fuses, may invalidate your
product warranty and result in product damage.
