TubeDepot Bias Scout Kit
The average bias job costs $40 - $60. Build your own bias adapter with our TubeDepot Bias Scout kit and you'll save money every time you set the bias on your amp.
This kit includes all the parts to build a single octal socket TubeDepot Bias Scout. Used with a basic multimeter (Get Yours Here)
, the finished adapter will allow you to measure both cathode current and plate voltage of a single tube position.
We recommend purchasing two of these kits so you can easily monitor both halves of a push-pull circuit.
Note: this adapter, as designed, will NOT test 7591 tubes.
