Fuse

The power transformer of the PV10A is protected by a fuse on the ac
power line (mains). A failure of this fuses is a symptom of a more serious
problem, and a competent service technician should be consulted. The
fuse is located on the printed circuit board, near the transformer. 

In no

event should the fuse be replaced with a value or type different
than that originally supplied. The correct fuse value is:

PV10A (with phono):

100 or 120V AC    3/4 amp, slow blow
220 or 240V AC    1/2 amp, slow blow

PV10AL (line stage only):

100 or 120V AC    1/2 amp, slow blow
220 or 240V AC    1/4 amp, slow blow
