UPDATE: Tubes tested. Canadian Philco Radio: ID and repair needed
#25

You can touch the grid cap on the 1H5 (grid cap is the connection on the top of the tube). That will inject a 60 cycle hum in the audio amp. If working will buzz loud. Replace the 680 ohm resistor it's part of the grid bias network for the output stage.
