I'm a little confused (a normal state of affairs for me).
I now see you are using a 1C6 (somehow I had in my mind a 1LC6... go figure). Looking up this tube, I am seeing pins 1 and 6 as filament. From there it goes Pin 2 = Plate, Pin 3 = G2 (osc. plate), Pin 4 = G1 (osc. grid), Pin 5 = G3 & G5, Top cap = G4 (signal grid). This is from pin 1 (the first large pin) clockwise.
