Hi, I have a problem with my generator 8110a with one 81103A channel, sometime positive amplitude have some compression, it is an intermittent problem and no correlation with temperature, period or amplitude ajustment. I followed signal on PCB 81103A and found that problem came from PCB amplifier (piggy-back PCB). Part number is A3424-01161. All components are discrete and maybe easy to find original or equivalent parts, but I don't have any schematics for 8110A, 81103A or piggy-back PCB amplifier. Somebody have a schematics or have an idea what is it the problem? Thanks
