GIVE YOUR FAVORITE MUSICIAN THE GIFT OF GOOD TONE!!!KEEP YOUR VINTAGE OR NEW TUBE AMPLIFIER IN TOP WORKING CONDITION!!!THE ORIGINAL, AND STILL THE BEST!!!THE HIGHEST QUALITY AND MOST ACCURATE BIAS TOOL, IN A DUAL SETUP FOR EVEN QUICKER BIAS ADJUSTMENTS!

You arelooking ata top quality Dual Bias Tool by SRS. The world famous SRS BiasTool in a dual setup, for one-step bias measurments in any push-pull tube amplifier. Two BiasTools connected in a rugged custom switchbox, with test leads- connect to your meter, to bias your amp and check both sides of your push-pull circuit without powering down! The two probes are completely isolated from each other, giving precise readings of either tube at the flip of a switch!

In case you don\'t know what a BiasTool does, here is some info:

With the ever-so-wide quality range of current production tubes, and the \"spin the roulette wheel\" world of NOS and vintage tubes, it pays to know how your amplifier is handling those expensive tubes you are putting in it. Even with tubes that are \"matched\" from the factory, you can still wind up with problems if you just plug \'em in and go. Enter the SRS BiasTool- a great device that no tube amplifier owner should be without- even if you decide to let the pros do all of the work inside of your amplifier, the BiasTool is an invaluable item, providing a quick indication of how your expensive output tubes are working in your amplifier...

The BiasTool testing probe works with most tube amps, including Marshall, Fender, Ampeg, Hiwatt and many others, measuring the amount of current which actually flows through your power tubes, using your volt/ohm meter, which can be purchased separately for as little as $15 dollars, depending on which model you prefer(we do have meters available, please inquire if you need one). The BiasTool is an indispensable piece of test equipment, used to check and set the \"idle\" of your amplifier, to guard against premature power tube failure due to overheating, and to get the best tone out of your amp...Setting your amp bias to run too cold will make it sound harsh and gritty, and setting it too hot will lead to premature power tube failure, and will not sound very good either- the BiasTool will help you keep your amp running the way it was designed to run, and sounding the way it was meant to sound!

This quality piece of equipment definitely falls in the category of items that require a working knowledge of amplifiers, especially if you are planning on making the adjustments yourself- we strongly suggest that if you aren\'t up to speed on such things, that you only use the probe as a measuring device, and enlist the services of a pro for actual bias adjustments- In this way alone, it can save you hundreds of dollars over the life of your amp, by keeping your output tubes from failing early due to poor biasing and overheating- it could even save you the cost of a new output transformer! If you are aware of the potential hazards which exist inside of a tube amplifier chassis, and are amp tech savy, you can save yourself the cost of a bench charge every time you re-tube your amp, saving you hundreds more!

Keep your new or vintage tube amplifier sounding great, and get the best performance and the most life from your expensive tubes! You can also measure the current draw of several tubes, to pick a set that draw similar amounts of current, electrically \"matching\" your own tubes! Works with 5881, 6550, 7027, 8417, 6V6, 6L6, 6CA7, EL34, KT66, KT77, KT88, KT90, and many more!
