I imagine most may already have a way that works for them but I am just thinking of newer folks trying to build up some test equipment on a budget.
This might help some on their benches with setting driver/final bias. Surely you can do it with a DMM but some might consider this to be convenient.

I just received what you see below.   A 100 mA DC ammeter WITH the appropriate plastic case ($9.95) and a set of clip leads ($4.50).

These are from a website called "Electronix Express" and I believe that they are in New Jersey.   Took slightly less than a week to get down here to Deer Park, TX.

The only thing I might say about the meter is that it is AWFULLY light in weight... but it IS just a meter movement and a light plastic case. I am thinking of removing the thin bottom plate (plastic!) and fashioning a more substantial piece of pine and painting it black to give it a little more "heft".

[QUOTE="guitar_199, post: 854701, member: 18156"] I imagine most may already have a way that works for them but I am just thinking of newer folks trying to build up some test equipment on a budget. This might help some on their benches with setting driver/final bias. Surely you can do it with a DMM but some might consider this to be convenient. I just received what you see below. A 100 mA DC ammeter WITH the appropriate plastic case ($9.95) and a set of clip leads ($4.50). These are from a website called "Electronix Express" and I believe that they are in New Jersey. Took slightly less than a week to get down here to Deer Park, TX. The only thing I might say about the meter is that it is AWFULLY light in weight... but it IS just a meter movement and a light plastic case. I am thinking of removing the thin bottom plate (plastic!) and fashioning a more substantial piece of pine and painting it black to give it a little more "heft".
