I was able to repair the detector coil primary and the 44 gets plate voltage now. Primary resistance is 1.4 Ohms.
When I apply a large signal to the antenna connection, it is visible at the 44 grid but all that appears at the 44 plate is a small amount of the modulating signal and no RF. Voltages are correct and 44 tube is good. Suggestions?
