Restoring a 46-1226 Code 125

After doing a check-out of the unit I find that both the radio and the phonograph functions exhibit a severe distortion when the volume is turned up beyond a certain point. I need to check the volume control for a possible cracked carbon trace - perhaps open above a certain point of rotation. Otherwise it may require connecting an oscilloscope to find where the distortion begins. I first thought some time ago that it was due to weak audio output tubes, but replacements from a known good amplifier proved that not to be the case.
More to come on the distortion investigation.
