1949 Motorola 5A9M - klondike98 - 05-10-2025

This is a nice little Motorola set that appears to be in relatively good shape. None of the external plastic case is broken although the power cord has been cut off.

The outside is very dirty but seems to be cleaning up nicely with some waterless hand cleaner on a paper towel, well, lots of paper towels and cotton swabs.

So far the only obvious broken parts are the two red plastic mounts for the front door hinges.

Here's a close up of the hinge inserted into the space where the hinge mount should be supporting the hinge. I'll have to do some thinking about out to manufacture something to do this. Since the on-off switch for the responds directly to the opening and closing of the front panel on the radio its important to find a fix.

The underside of the chassis has a nice date stamp of May 4, 1949 and when that panel is removed you get a look at the wiring and components housed there. A lot of stuff packed into a small space so replacing caps is going to be a little difficult.

Fortunately it looks like all the transformers are still intact (unlike the Philco 39-7 I just set aside),the tubes all test out OK and the loop antenna housed in the front panel ohms out OK.
