Advice for restoring 38-12
#6

Just processing the order for the 38-12 and the schematic shows Field Coil at 1,500 ohms D.C.

Primary winding of output transformer is 450 ohms. Nothing given for secondary. If a winding is
open it will be the primary where all the DC current is for the output tube plate.

Most likely, either cap #21 shorted or the 41 output tube to pop the primary winding open.
