Replaced the multisection cap, got it up to full power. A section of the video phase splitter tube (12AV7) started red plating, found cathode voltage was very low (swung under the grid) because the matched plate/cathode resistors had drifted from 1k down to around 100 ohms. They will need replacing before going any farther.
