Here's a pdf of a Crosley 9-408 owners manual if anyone needs one.

Check out the service contract that came with it, from 6-1948-6-1949,
also note the serial number, 170! I thought mine was pretty low at 2500.

The 9-408 in the manual looks just like my Crosley 307TA. I went to the Rider books and the 9-408 schematic is in Volume 2 but for service information it says to go to volume 1 and look at the 307TA service information.

Here is my 307TA.

Thank you for posting the manual.

There are some fairly subtle differences between the 307TA the 9-408 and the 9-420M mostly in the grille cloth and the knobs.
