[Hammarlund] HQ-120X S-meter

[Tom]

Hello,

I have an HQ-120X on the workbench with a damaged S-Meter. I am looking 
for a suitable substitute. This S-meter is a Tripplet brand movement 
with an Hammarlund scale and logo.  The Tripplett model number is unknown.

I apparently have three options. The first, and best, is to locate a 
replacement from a junker 120. The second, less desirable, one is to 
modify a similar meter to replace the original one. The problem here is 
determining the parameters of the Original movement. All I know is that 
the original meter has an internal shunt of around 4 Ohms.

The third option is the worst one. This one is to try to rebuild the 
original using replacement parts from meters out of my junkbox.

Any suggestions?

Tom
