Used to be a member of this forum a few years back, and have just re-joined, and this is my first post. I have hunted online on Ebay etc for decent air spaced tuning capacitors and apart from used ones there seems very little available. Has anybody had luck with suppliers of new ones at reasonable prices? (for use on receivers) As I am now retired and have time available, I am seriously thinking of constructing one, as I have good access to CNC and metalwork machinery. Just wandered if anyone has tried to construct one?
