So have a SA-7500II I acquried. Previous owner said it was in the 'needed work' pile. After a cleaning and initial checks, I fired it up and it did come out of protection, had clean sine waves on both channels. But then after a couple of minutes, the protection relay would click on and off, randomly doing so.
I checked for DC on both channels when the protection relay was off and each channel had less than 50mv... At this point, would it be safe to assume that the relay is just bad and needs to be replaced? Or could something else be amiss? I already ordered a replacement relay, but was wondering if there is anything I should check before/after/during relay replacement
