Fuses
The
CAV45
power transformer is protected by a fuse on the ac
power line (F1, located in a compartment in the ac line-cord
receptacle mounted on the back of the amplifier), and by four
separate internal fuses on the secondary circuits of the transformer
(F2 – F5) located on the bottom of the pc board. A failure of any of
these fuses is a symptom of a more serious problem, and a
competent service technician should be consulted. In no event
should fuses be replaced with a value or type different than that
originally supplied. The correct fuse values and types are:
F1: 5x20mm 5 amp T-type if configured for 120V:
5x20mm 3.15 amp T-type if configured for 220/240V.
F2, F3, and F4: 5x20mm 200 mA amp T-type
F5: 5x20mm 3.15 amp T-type
The output stage is protected by a plate fuse in series with the
output tubes. This is a 5x20mm 800 mA F-type (fast-blow) ceramic
fuse, located inside the chassis in fuse holders mounted on the
vertical power supply board.
