Two Questions
#3

Hi All;
Morzh, Thank You for your Answer..
Which I am still a little confused about and here's why.. On my Breadboard set up I have had the Tube wired up as per Your Answer, and I got the funny lower voltage across the Dropping resistor, about 50 Volts (If I remember correctly).. When I temporially shorted the resistor with a jumper clip wire, One of the Grids started to "GLOW RED" and I quickly removed the jumper..
After wiring all pins just the opposite (side to side) The Dropping resistor showed about 120 to 125 Volts just like it was suppossed to.. And after some tweaking as explained in my Oscillator posting, I got the Oscillator to work.. So looking from the Top of the Tube Down starting at pin 1 (left side) which is a filament pin.. I have plate (P), Grid 1 (G1), Grid 2 (G2) and Grids 3 and 5 (G3,5) and pin 6 final filament pin..
Am I reading your Answer correctly or If this is backwards "Why" does it work this way and not wired the other way ??
THANK YOU Marty
