Well guys, it cannot be fixed. I got the bad news today from Eldad. 
The analog meter movement is not just sick, it is dead. The armature 
winding is open. I am now in need of a replacement movement. It has 
been determined that it is a 200ua DC movement and is commonly used in 
other Heathkit test meters. I have a pic of the original which I can 
send if anyone needs it.

If anyone has a movement that they wish to sell and has been tested 
ok, please let me know. First I will try to use the same meter housing 
and will just replace the movement if possible before I consider one 
that requires a custom designed face to put in a complete meter made 
for other equipment.

I know that the needle should be the same length as the original but I 
am willing to trim one that is too long even though it will affect 
accuracy because the weight of the needle is part of the design. Just 
a little trimming should not affect the the accuracy too severely.
