That's basically what I did for the pair of meters I have now. I started
with a pair of 1A DC Triplet meters and converted one of them to a 15VDC
meter. I managed to snag a 0-15V faceplate for it so it looks great. The
problem comes for the amp meter. I wanted something greater than 1A and
couldn't find a suitable faceplate so I started over.
This little "Signal Corps" Simpson meter is just the ticket; but it leaves
me wanting that "matching" volt meter. I may have to settle for a mismatch,
though. I'm going to sit back and keep watching for what I want. Maybe
I'll find one.
Thanks,
