Fuses

The Premier Fifteen has two power transformers (one for the tube
circuitry, one for the control circuit), each of which is protected by a
fuse. A failure of either of these fuses is a symptom of a more
serious problem, and a competent service technician should be
consulted. 

In no event should these fuses be replaced with a

value or type different than that originally supplied.

 The fuses

are located on the small pc board mounted near the larger power
transformer. F1, the fuse for the tube circuit transformer is located
nearest the transformer cover. The correct fuse values are:

If configured for 100 or 120V:

F1    3/4 amp, slow blow
F2    1/2 amp, fast blow

If configured for 220 or 240V:

F1    1/2 amp, slow blow
F2    1/4 amp, fast blow
