Replacement Tube Selection & Bias

This amplifier features Yorkville’s auto-balancing / auto-matching tube biasing technology. As a result, when the time comes to replace the tubes in your Yorkville amplifier, there is no need to pay a premium for a matched set – nor does the bias need to be adjusted when you use a different brand. We make no claims as to which brands of tubes might sound best, but with auto-balancing / auto- matching, you are free to experiment without any need for concern that the amplifier or tubes will be distressed. Please note that auto-balancing / auto matching cannot fully compensate for different types of tubes - 6L6/5881s versus 6CA7/EL34s, for example.

Please note that although auto-balancing / auto matching allows you the freedom to select unmatched tubes from a variety of manufacturers, it may not be able to fully compensate for the use of a non-equivalent model or part number of tube

– 6L6/5881s versus 6CA7/EL34s, for example. Use of non-equivalent tubes may result in unpredictable performance.
