As long as the Shadow Meter coil has continuity and is providing B+ to the DET-OSC and RF tubes, you're fine. It does not need to make a shadow to allow the front end of the set to operate. The Shadow Meter is the least of your worries at this point.

If, by chance, the coil is open, then sub in a 1.5K, 1/2 w. resistor during this phase of your repairs.
