No pops from any grids. On the 12AY7 pins 2 and 7 grids are silent. I get a lot of noise from pin 6 plate, voltage now 125v DC. The other plate pin 1 on the 12AY7 is silent. Voltage there is 138v DC. On the 6V6 Pin 5 grid is silent also. I get a little noise from pin 4 screen. Sorry to be confusing, but I misread the pin #s in my earlier post. Its the grid that is slowly ticking up in voltage which makes sense I guess. I turned it off at about 158mV. So electrons are building up on the grid, correct? They should be passing through it seems maybe?? The cathode is near perfect at 20.6v.
