Re: [Amateur-repairs] Old test eqpt? Chuck it? Refurbish it?

A vintage German broadcast receiver that I have uses a grounded metal vane on a rotating shaft in the vicinity of the main tuning capacitor to create a fine tune control. Moving the vane closer to or farther away from the tuning capacitor changes the capacitance enough to make a decent fine tuner. One would need to take care that it can't actually touch the main capacitor of course. I thought it was pretty darn clever when I saw what was going on.
