Valve Crystal Oscillator Grid Current

[John M0GLN]

My take on it rightly or wrongly is what I suggested in my earlier post, the grid forms a capacitor, AC current will flow via that, the reactive part of that capacitor will not dissipate any heat, only the R component of that capacitor will, we have to differentiate between any DC grid current and the AC current flowing through the grids capacitance.

Lawrence.

Thanks Lawrence, I think I'm up and running now with that explanation.

Thanks
