Thanks Tony, excellent explanation as always.
That 6uF capacitor is way bigger than anything I tried across the secondary. Which got me thinking, on Marks set up that capacitor is on the control board and connected by longish leads out of necessity to the secondary.
On my set up that 'tuning' capacitor is right on top of the toroid and connected by the shortest possible leads.
Does the lead length make much difference? Intuition tells me yes but I might be wrong. Klaus
