Hi Bob,
Most likely a bad RF coil. Check the RF amp plate to see if it has voltage. If not...you've found the culprit (the coil connected to the plate of the RF amp tube).
If the RF amp tube does have plate voltage, then the antenna coil is likely faulty (open winding).
The IF of the 91 is 260 kc so you're in the ballpark.
