Replace the meter bulbs on a NAD 3080?

Anyone done one of these or something similar? I'm not sure how to open the power meters to get at the bulb. Someone's done it before and cracked one of the cases a bit. There is a small screw in front but loosening it doesn't seem to open the case. I can't even see the bulb...I guess it's in back.

Any insights? Type/voltage of bulb?

Many thanks.

I'm afraid I don't have any details for the meter bulbs, but I would caution not to tamper with the 'screw' at the front of the meters at all - I'm fairly sure it's for fine adjustment of the meter, and is almost certainly attached to a very small, very fragile, internal spring within the meter movement... hopefully "loosening" yours has not broken it.

Yipes! I'll check to make sure I didn't screw it up. Thanks!
 
The few times I've needed to open up a meter such as those, the clear lens was affixed to the housing by clear plastic tape along the meter's edges. The clear lens lifts off once the tape was peeled away.

Cheers - seems like a good recommendation (filed for if/when mine need doing) :thumbsup:

When I opened the meter case I didn't see any attachment between that small "screw" and the meter, though. The meters still seem to work fine however. Does the manual say? I haven't read it.
 
I'm about to take the 3080 light project myself. This is what I ordered to do do the job. Decided blue instead. Any last minute suggestions for cracking open the case? What are the methods from the factory to bind the case together? ie tape, a little glue? Any experience with this would be greatly appreciated. Mick
