HP8591E input attenuator problem

I seem to have a problem with the input attenuator. The 20db section is intermittant. Sometimes I get 20db sometimes its all over the place. Sometimes it passes amplitude cal sometimes fails. The control signals are good. The unit in question is a Wavetek 0955-0453. Has anyone been inside one of these? I have the RF assembly out and on the bench, I suppose I will take the attenuator out and run some tests on it to verify the problem first.
