Signal Generator Help Needed
#5

Hi George, so when you connect the ground lead of the signal generator to the radio chassis that doesn’t kick out your GFCI but touching the .22ufd cap to the control grid does! Icon_eek That indeed is strange. If your new generator has a 3 prong plug with ground, try using one of those 3 prong to 2 adapters and as mentioned earlier, make sure your isolation transformer is indeed a true isolation! You can ohm it out to see there is no connection between the AC power input leads and the output!
