I decided to remove the dial cord and inspect the control spindle. It was covered in patches of surface rust so I fired up my rotary tool and removed the rust with a wire wheel. Once the control spindle was smooth I restrung the radio and the bunching stopped. It looks like the rust was causing excessive friction on the control spindle, resulting in bunching. The cursor 'floats' on this radio.

I also restrung the FM tuner properly.

The radio is working well without any hum. HT is sitting at 220V. I'll check all of the valve voltages later on. I'll also look at realigning the radio.
