[Station X]

I'm not familiar with the construction of the tuning capacitor in this radio. If you look at it you may see some brass colloars on the rotating shaft between the vanes. These will have a groove machined in them and sitting in the groove a springy wiper. Carefully apply Servisol making sure not to get it between the vanes. Then rotate the shaft from stop to stop several times before the cleaner evaporates.
