Description

Proudly made in the USA! No offshore junk here- these are built to last... You are looking at a top quality original SRS Dual BiasTool, new. Used world-wide by tube amplifier technicians for correct measuring of bias, a critical measurement and adjustment required when installing new output tubes in a tube amplifier. This dual unit can check two tubes at one time with one meter, without the need for powering down, waiting to cool, and switching to a different tube. Great for any tube amp, including vintage CBS-era Fender amplifiers with "bias balance" circuits- saves time and sanity. Works with 5881, 6550, 7027, 8417, 6V6, 6L6, 6CA7, EL34, KT66, KT77, KT88, KT90 , and many more- if you are unsure, or do not see your tube type listed here, please contact us prior to purchase to verify if this device works with your tubes and/or amplifier, and we will gladly help you out. This listing is for the Dual BiasTool only, brand new. The meter and amplifier in the picture are not included.
