Think you meant model 39-85, the 39 indicating year 1939.
Below is the schematic link. Uses 2 batteries, 1.5V high current for the filaments and 90V low current for the plates. However the batteries are obsolete but a 1.5V D cell and 10 transistor batteries wired in series will work assuming they will fit inside the radio. Richard
