PL400 VU Meter

[Brettl]

I still have 1 meter that is lagging. Does anyone make a replacement?
Other than that, the build is finally complete!!!!

Just wondering my meters are 1972 and have 6 fuse bulbs 3 below and 3 above and they are useless. What are my options?

Gary, check out the GeorgeP solution in post 25 of the link. He put together a nice PDF.

Joe showed some nice prototype WOAD mechanical meters in new faceplates a while back.

Lagging meters can often be caused by the hold down screws being over tightened. Loosen them a bit and see if it helps. Is the meter pointer dragging across the meter face? Sometimes the meter movement is just dirty and this causes the meters to act sluggish, they are over 50 years old.
Some folks on this site are talented enough to disassemble, clean, and reassemble these meters. They do it because there are no replacements.
