Today I went through the AM and SW alignment again just to be sure I have it right. AM was pretty close but shortwave was a bit off. But I still get no shortwave. I tried running a wire out the window and into the back yard but still nothing. Still nothing on FM either.
On the positive side, yesterday I received the 3 tubes I ordered (7F8, 6BA6, 7R7) so I decided to pop them in and see if there was any difference. I get more volume (although it's still not where I think it should be) and I can detect a couple more faint signals where there was none before. I bought a tube tester off Craig's List and will go pick it up next week and test the rest of the tubes. Will tube replacement affect alignment?
Here's something pretty cool. I'm missing one of these spacer/eyelets for mounting the pushbutton assembly:
My new 3D printer is supposed to be here sometime in the next couple of weeks so I drew up a 3D model for one and will try printing one:
I also broke the stiff cardboard/fiber shield under the pushbuttons when I took it off. I assume this is some sort of light shield? Anyway, I drew up a 3D model for that as well, so we'll see how that turns out.
