Hopefully you can find direct replacements.
A few years ago, one of my blockbuster meters was dead so I decided to try my luck on a set from ebay just like these
VU meters.
I replaced the originals with the donor meters.
It was a major pita but in the end they worked out.
The only difference was that the new ones were orange instead of white.
I tried running a brush with white paint down them which looked great but the needles barely moved.
I had to clean them both off and leave them orange.
I never thought the weight of the paint would be too much.
Live and learn, lol.
