Here it is all wired up and ready for power. There are a couple modern resistors in series in the back right.
It had already been replaced with a modern resistor when I got the radio and I wasn't sure of the wattage.
Once the radio is working, I'll see how hot it gets and create an appropriate dogbone.


I added a 2A line fuse and a 60W bulb (Dim Bulb Tester) and turned it on.
The B+ came up to about 500 then settled down to 250 - no smoke no flames
Also no sound until I added an antenna. Once I did, I was treated to some familiar local AM stations

I removed the DBT now that I knew I didn't have any shorts. That got the B+ up to about 350v like it's supposed to be.
AM is very strong and clear now, but still no SW.

I loosely coupled an RF generator to the antenna input and scanned through the 1.5-4 MHZ band. Still nothing.
I suspect the LO isn't running in SW mode. Time for some troubleshooting.
