[QUOTE="warlok, post: 92505, member: 2626"] Just grabbed a 2008 Plexi module cheap but couldn't try it before buying. Put in my RM100 and sounds almost the same as my KH1.. Low output and no gain.. Stuck the ol' multimeter on the gain pot and it's dead. And the level pot has a hard spot while turning past 4-5, and reads at 0 (min) = 152 ohms, 5 = 196 ohms, 10 (max) = 0 ohms. As in there's a hump as the pot is turned and I don't think that's the right value anyway... it's on it's way out.. I could get my money back but I can fix it and I got it cheap. Before I go taking it apart, Anyone know if the values on a 2005 are different from a 2008? From Graham Pearson's spreadsheet: Plexi (05/05/05 Values) VR1 (Gain) - 1M VR2 - 1M VR3 - 25K VR4 - 250K VR5 (Level) - 500K Thanks.. [/QUOTE]
