40-201 oscillator not working.

I'm good with your readings, the triode is conducting, although a little high. So back to oscillation. I have 2 more thoughts. The 26 coil is BC band but is a separate coil from 28 which is the primary. Is it possible that they are not close enough to get "excited"? Can they be moved closer together? Additionally, could the connections to 28 be reversed? Polarity is important to sustain oscillation. How did the tube pins look?
