When you run out of things to buy, I have a volume/balance harmonic rubber band looking balancer that goes between the posts for these knobs. With proper installation, also available, these harmonic springs can make your $2000 wood knobs add a new dimension to your bragging rights. Only $4000, including a one owner, rebuildable Supex 900 Mark IV. The cantilever is slightly bent, but it works well on my uni-pivot arm, when properly tweaked to one side. Hell, I'll even throw in the arm (Formula 4 JH clone of Mayware). For the price of a plane ticket, dog sitter, and hotel, I will come install it.
