Thank you for your response and confirmation. I did connect the electrolytics to ground and applied shrink tubing. I'm going to take a look at P/N 21 (filter bank). I believe it is different on the Code 123 (one less capacitor). Working with the Code 123 is challenging and figuring it out as I go given the lack of a schematic. This set does not oscillate and also looking at the oscillator coil that doesn't meet the ohms specifications (but again I'm looking at the specs for a code 121 and I believe the code 123 that I'm working on has a different oscillator coil
