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,
