Philco PT-39

Can anyone direct me to a tube diagram for a Philco PT-39. I received the radio in parts, the sockets are not marked and my Riders does not show the chassis diagram.
Thanks,
Jon.

May have to trace the circuit to determine tube locations? The 35A5 will be wired to output transformer which drives your speaker. 7C6 connects to volume control and input of 35A5. Next will be 7B7 probably located between two IF ttansformers. Connected to the tuner is a 7A8. 35Z3 is the rectifier tube. Line cord will be wired to this tube and it will connect to filter caps. Less pins will be used on this tube socket.
