I once posted a thread about how I built one with an LND150 and thought it sounded pretty good. I've refined the idea a little further and I thought I'd mention what I was thinking and see what people thought.
A cathodyne splitter made with a mosfet like an LND150 is capable of almost 1/2 of V out to each output- meaning if you have a 300 volt supply, it should be capable of producing 150 volts peak to peak at each output before clipping. I'm assuming the cathodyne is fixed biased for this example.
So why not use a resistive divider at the input of the solid state cathodyne so that it can't ever get more than 1/2 of B+ at the input? As I said before this should effectively remove phase inverter distortion from the equation up to the point where the output valves start to draw grid current.
Am I missing anything? Could be a neat way to go!
thanks,
jamie
