Fuses
The ET7 has two power transformers (one for the tube circuitry,
one for the control circuits), each of which is protected by a fuse. In
addition there is one fuse on the ac mains. 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 these
fuses be replaced with a value or type different than that originally
supplied. Two of the fuses, F1 and F2 are located on the main pc
board near the power transformers. The third fuse, F3, is in a tray
that is part of the IEC power line connector. The correct fuse
values are:
If configured for 100 or 120V:
F1
F2
F3
If configured for 220 or 240V:
F1
F2
F3
