Balanced Audio VK-655SE - Manual (Page 10)

Each channel of the VK-655SE is protected by three fuses:
1. The main line fuses are located on the back panel. These fuses should
be checked if one of the front panel LED’s fail to light.
2. Two internal fuses are mounted on the amplifier circuit boards. These
fuses have two green LED’s associated with them. Both LED’s should be lit
when unit is ON and operating properly. Failure of either of these LED’s to
light indicates that the corresponding fuse is open.
CAUTION:
Make sure that the VK-655SE is turned OFF and disconnected from the
power line before checking or replacing fuses.
A blown fuse in the VK-655SE is potentially an indication of a serious
problem. If a replacement fuse fails as well, no further attempts at servicing

service.
