schematic four-tube

Hi everybody

I wonder if I could find a schematic of an American 4-tube radio with valves 47-57-58 and 80 to find out if there are some equivalents (similarities) with my Weser Bros. set of 1933-1934. One remark: the potentiometer goes to the cathode pin (58).
This would give me the opportunity to give the set and the schematic to a technician over here.
Many many thanks

Hi Marc

Try this schematic for Automatic Radio P25:

A #24 tube is 5 pin version of 57 and 35 is a 5 pin version of 58. Drop the first digit in tube numbers, 247 is 47.
