MFJ 962C Tuner

This is the tuner that I have grown to hate. When I first got it, it worked fine. I got this tuner because it was supposed to handle my amp. Now I cant say exactly what is wrong with the tuner other than the fact that it works when it wants to. I like to think its something in the SWR circuitry that is causing the problem, however I'm not positive. Anyway, this is what I use for a tuner when it decides it wants to work!
