What are the symptoms you would see to indicate the need for this fix. The dimmer in my Mk2a is freaky in the sense that the VFDs luminance sometime doesn't correspond to the dimmer value. My Mk2 has no such problem.

Yes, I read the FAQ entry:

If, when setting your dimmer, the display seems to flicker erratically and select random levels of brightness, this is a known problem with some players.

however, my display doesn't flicker. Here is an example of what it does (my dimmer is set at 100% and 60% with lights on)

I get in the car and boot Empeg. Display is dim (not 100%). Turn lights on and display is brighter (should be dimmer). Turn off lights and display is now proper 100%. Turn on lights and display will now be proper 60%. After the initial wrong values following boot, turning lights on and off now result in proper luminance nearly everytime.

What I'm trying to say is that once the player is set to a value, regardless of wether it displays the proper luminance, it will not flicker. But, it is often the wrong luminance.

I will perform this mod no problem. I just want to know if I would be correcting the right issue. Thanks.
