Not so good news...

It doesn't work right.
At first it would not pick up anything.Then I noticed that the filament of the first audio amp, a 6J5G, was not lit. And I had just tested it! Well, I had a metal 6J5 on hand and stuck it in the socket instead.
Now, it made a little noise. It receives nothing on AM, or on SW bands C or B. It works on SW band A, as I was able to tune in a few stations including WWV.
Oh, and I found out that I wired the tone control backwards. That will not be difficult to fix, though - I only need to switch two wires around.
Time for further testing...
I aligned the IFs and that was no problem. With the radio set to the AM band, I tried injecting a 640 kc signal at the grid of the 6J8G det-osc tube. The radio received the signal. I then moved the generator to the grid of the RF amp. The radio still received the signal. But with the generator on the antenna terminal...nothing.
Like I said...time for further testing...
