Assuming that you have emptied out and recapped the bakelite blocks, I suggest that you replace the largest (power) resistors- the ones electrically connected to the filter caps.
Most likely it's one of the large power resistors but if you want the radio to operate well, the highest values must be eventually replaced- generally all resistors above 20K. Work you way down.
You could also isolate the resistor with a can of freeze-spray. A light spray on a bad resistor will thermally shock the resistor into doing something better or worse. A good resistor will not be affected by the freezing spray.
