The tuner cleaner only made the broadcast and other bands clearer, nothing on shortwave except an occasional weak station, but it is a shortwave one because it does the usual drifting in and out. The schematic shows that the oscillator coil is the same one for both bands, but there is a SW "transformer" coil that shows on it also. Should I spray that also or could it possibly be open? Is there a way to bypass the oscillator coils? I know on other Philcos with 'Cap' tubes, you can bypass and attach a wire to the oscillator tube. Any assistance is appreciated.
