As far as the Focus Voltage project goes, I am still trying to work out how best to set it up in order to prevent loading the G2.
I have the 1 megaohm potentiometer that purchased for this project, along with some various power resistors, the largest of which is 27k 2W. I can always buy another couple of resistors, but I'd like to do it with what I have on hand.
The original Focus circuit has a 470k 1/2W resistor in series with the Focus Grid. I'm not entirely sure if it's capable of handling a modified circuit that includes a resistive divider to pull down the focus voltage, but this is what I'm currently thinking about
:
I also have some 1.6kV 1.5A diodes I could maybe use to isolate the G2 from the Focus voltage circuit, maybe preventing the load down?
Any opinions or advice on this?
TIA
