Please read before buying.Two separate issues cause "bouncy" action with these meters, particularly in original UREI Rev D and E 1176LN versions and UA reissues. The Modutec meters used in these builds suffer from aging issues -- as the internal mechanism and magnets age, mechanical damping is reduced. This causes the meter needle to overshoot when moving up or down. Also, in GR mode, these three 1176LN versions use a balanced bridge circuit that has a positive feedback (hysterisis) effect, which greatly exaggerates bounce. In most cases, meter action in a 1176LN Rev D or E or UA reissue in +4 mode appears normal, but GR mode exhibits needle bounce.We carefully test these meters. If excessive bounce is seen, we have a meter repair shop re-charge the magnets and adjust the meter damping resistors. However, this is just a partial fix -- the meters operate properly in +4, but will still bounce in GR mode. We've been unable to find a better solution to this, and new meters are totally unavailable.Later 1176LN versions (revisions F through K) use an opamp in the GR meter driver, which buffers the meter mechanism and avoids positive feedback problem. Unfortunately, there is no simple, elegant way to modify or update the earlier versions.Please be aware of these issues if you are replacing a meter in a black face 1176LN. If you're replacing a meter that's dead or damaged, or sourcing a meter for a DIY project, there will be some degree of bounce, especially with Rev. D or E circuitry. (UA reissues are Rev E.) If the meter in your unit works but is bouncy, replacing it with one of our meters probably won't yield any improvement.
Original Modutec VU Meter For All UA UREI 1176LN LA-3A LA-4 Blackface Models. This is an exact replacement meter for the black face limiter models. It has been refurbished and tested in both AC and DC modes, for correct operation in +4 and GR modes. It includes a new cover, and will have an excellent appearance when installed. Item will be packed well and is guaranteed to work correctly.
Front of meter (cover) is 2 15/16"" wide, 2 1/4"" high.
If mounted with optional bezel, typical panel cutout is 3"" wide, 1 5/8"" high.
If mounted without optional bezel, round mounting hole is approx. 2 1/8"" diameter.
Depth is 1 7/8"", including rear terminals.
PLEASE NOTE: These meters were not originally manufactured with the UREI logo on the scale, and original meters with the UREI logo are no longer available. These are the exact same Modutec meters that UREI used, and we have affixed a small adhesive label with the UREI logo. The are a close match, but don't look exactly the same as original UREI meters. However, if you are replacing a faulty UREI meter, it is not difficult to remove the meter cover and move the scale from your old meter to this one.
We also sell replacement bezel assemblies for this meter, for panel mounting. They are in our store in the UREI and UA Parts category.
