I finally got time to get back on the project. I had the the new caps to replace #31 hooked up all wrong. Once I studied the schematic I was able to figure out how they needed to be hooked up.

I have the radio playing and it works very well pulls in stations good, and the shortwave is very sensitive. Also cleaned up the chassis, painted the power transformer bells, and shined up the IF can and old E-Cap shells.

The power transformer gets a little hot so I'm working on figuring out what value/wattage dropper resistor to put in line with the power cord. I tried a 50ohm/50W which seems to do good drops the input voltage from 125 to ~110.

Here is a couple pics.

I added an input for an MP3 player or phone to the back of the set.

Now to start on that cabinet.
