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:

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.
