Have the 3rd I.F. can, part #42 open. Suspected open coil, but it is OK. Schematic shows two 100mmfd caps inside, #'s 42A and 42B, and #42C, a 47K resistor. The resistor is there but no caps.The black wire that grounds the two caps just dead-ends at pin. Does anyone know if this was a production change? If so, why did they leave the wire ? 99% sure radio left factory like this. I don't know enough to determine what effect this would have on circuit.
