1928 Atwater Kent project
#6

I guess I am lucky, but my AK 40 is still running on its original power supply filter caps. Being potted in tar, they seem to survive a bit better than one might expect. I did have to change a couple of the glass incased resistors though. One decoupling resistor under the PS terminal board and the detector grid leak. Other than those and the output stage coupling cap which was changed many years ago it is otherwise original and still works great.

One common problem with these radios is the audio interstage transformers, which as I have heard tend to develop open windings. Looking at the schematic, you can see that it is a very simple TRF circuit.

Here is a link to the photo of the workmen making the cabinets for your radio.
