Another experiment... instead of grounding the disconnected grid, insert a 470 k ( or so ) resistor between the grid and either end (try both) of the 330 ohm cathode resistor.

What I did was put the grid back on pin 5 of 25l6 then jumped from the grid to either end of the said 330 ohm resistor, the grid was put back on when I did this and it blanked out so now you want me to use a 470k or so resistor from pin 5 to either end of the 330 ohm resistor while the 330 is still in place, correct? So really it's just raising the value of resistance in that area. Ok I got it, lol between grid and the 330.
