GT Bias tool

Has anyone used a Gr__ve T_be bias tool to bias your amp?

Why the name redaction?

I have never used that one. I have a CompuBias and love it.

I have owned this for several years and have used it occasionally when retubing amps, I just wondered if anyone has used one in biasing their "clone".
I read through the archives and have seen the numerous posts on biasing the amp, and have absorbed what has been established and will go ahead and use by GT bias tool.

The name redaction was because I am not endorsing any products for any manufacturer.

I have not.

I use the Weber Bias Rite.

This isn't the Gear Page - you don't have to be that politically correct here.

what your thoughts on the bias rite? I have the version with optional switching and noval / octal. It's never really worked well for me. I gave up on it years ago. Learned to bias with a scope and transformer shunt. Now more times then not I a pair of compubias.

It gets me in the ballpark. I have a friend that works on tube stuff all of the time,ie.guitar amps, high end audio, Mac's, Dynaco, Eico,etc.. who likes tube stuff and I will run it by him to fine tune and do some tube rolling.

I have the same model as you, two octal and two noval connectors.

I hook it up, take readings and plug them into the Weber Bias Calculator. Then adjust to the recommended value(s). I'm a novice at amp building/servicing. I don't know near as much as most folks in this forum. I'm happy if the amp works, sounds decent, and the tubes don't red-plate ... so by that measure the Bias Rite has served my needs.

I concur!
