Fuse Protection: 
 
The circuitry of the VK-255SE is protected by the following fuses: 
 
1. The main line fuse is located on the back panel. This fuse should be checked if the 
front panel LED’s fail to light. 
 
2. Two internal fuses are mounted on each of the two 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-255SE is turned OFF and disconnected from the power line 
before checking or replacing fuses. 
 
 
 
A blown fuse in the VK-255SE is an indication of a serious problem. If a replacement fuse 
fails as well, no further attempts at servicing the unit should be undertaken. Please contact 
the factory for professional service. 
 
Fuse Ratings 
 
The proper ratings for the main line fuse are as follows: 
 
 
For 100-120 VAC Units:
10A 250V Slow Blow
 
 
For 200-240 VAC Units:
7A 250V Slow Blow
 
The internal printed circuit board mounted fuses are 10A Fast Acting type. 
 
 
Factory supplied fuses should be only replaced with the same type and rating parts.
 
 
Servicing 
 
The Balanced Audio Technology VK-255SE should not require service to maintain its high 
performance. In case of malfunction, if replacing fuses fails to eliminate the problem, please 
direct any further service inquiries to the factory.
