Operating the VK-55 Normal operation of the VK-55 requires simply turning the unit on. There are no meters to connect, bias setpoints to remember, or drifting bias points to adjust.

Replacing Output Tubes: To maintain the optimal performance of your unit, replace the 6C33C-B output tubes only with matched sets available from Balanced Audio Technology. If only one tube fails, then just one pair needs to be replaced. Please do not substitute any random tube as a replacement. Although the automatic bias circuit in the VK-55 will accept virtually any random set of output tubes, the unit will not be guaranteed to meet all of its performance specifications under such conditions.

Servicing: The Balanced Audio Technology VK-55 should require no service other than tube replacement to maintain its high performance. Please direct any further service inquiries to the factory. Cleaning: To remove dust, occasionally wipe the front and top surfaces of your VK-55 with a damp soft cloth.
