Hi James,
I have just the schematic and even those I think are partials, ie the Jones filter is a "box". Not high quality drawing, faintly printed.
Ten Tec would be the source of manuals.

But, have you looked on the web or You Tube videos, searching "Ten Tec Scout Meter repair"?

I would have to dig out my Scout, which is on "the wait stack", for repair of finals. (Field Day crowd ran the ALC too much).

As Mike Bryce posted here, the meter is held together with Scotch tape, as the case is two piece plastic. I think there is a serrated metal clip that surrounds the meter and then wedges it against the back of front panel. There is a flange on the front if so.

So you would take the whole meter out of the radio, then use an Xacto knife to cut along the case seam to split the tape. Then, the top of the meter should come off, giving access. Most rectangular meters of that vintage work like that.

There might be dust or some small particle stuck between the needle coil and the stator parts. I take a high intensity pen light and inspect the clearances in meters, by puffing gently on the pointer to move it up scale and look for what it is binding upon. Even before doing that, I might angle the meter toward a wood or other non metallic work surface and tap the meter gently upon the surface to see what might fall out. Not too hard, but enough to move anything out of the coil to stator area. Before you do that, do inspect that the pivot jewels are in the pivot areas. ( I just thought of a rare happening, a cracked jewel that had parts shed off, but not on a TT meter).

A lot of surplus stores had similar meters that could be adapted by replacement of the Ten Tec scale into another meter or swapping the new movement into the old Ten Tec housing. Or as Mike said, remove the meter and put in a LED bar graph. He can give you exact info on the full scale ma rating a replacement needs to have.

GL,
