    I decided to do the LED conversion do to the heat . My VU blue plastic looks a little brown when lit , I'm not sure if its just dirty or aged . If aged do you discard it and use the film ? not sure I want tot do that. The VU's do have small pieces of blue film to soften the original lamps . I guess what getting to is what have other people done ? thanks

    I tried the LED route, and didn’t care for it. I bought two sets, one with green LED’s that looked cheesy to me, and regular, white LED’s that were too bright. I just ordered the regular, incandescent bulb style lamps, and will go back to using them.

    In my case I discarded the old blue film and used 2 layers of new film on my MC2255 for a bit more diffusion and a touch darker blue. I really like the way it came out with the led upgrade.

    All I did was swap out the bulbs and its to "soft" on VU , I'll try removing just the original film off the diffusers . The lettering lights about the same , I have one intermitting on/off . I might be going back to incandescent .

    If you use the right LED's then you will have no issues.
    I use warm white for everything and use the original filtering, this applies to other brands as well, and I have had good results.
    Did you use drop in replacements?

    Sorry but in MC2105 and MC2505 there is no blue films , there is only one hard blue "plexi" just above outside the both meters

    I think this is the way to go kevzep . I ended up with the LED warm lights on the VU's only because I play the amp a lot and the black metal cover gets hot . I don't really think heat is an issue here as the heat is not directly in contact with anything. Those green funky looking LED bulbs for the lettering didn't look right on my MC 2505 . The lettering light was very uneven, maybe because only the LED on the tip on bulb was in the diffuser . These green bulbs do give off a nice light . I will use them somewhere.
    clinic-audio My MC 2505 has a piece of blue "plexi" across the face of both meters and one strip of blue film on the beveled edge on the two clear plastic diffusers on top on the VU meters . If you remove the film the meters get an uneven blue/white color .The meters look faded . I have seen this faded look on other MaC amps .I wonder if adding the film would help ?
