My RCA C9-4
#14

OK, I got impatient. I decided to use the glass 6J7 to give a rough test, so I put the 6J7G in, installed the 5Z3 rectifier and its shield, plugged in the speaker, and turned the radio on. No smoke, no fire, and after about a minute I could hear sounds through the speaker. I attached my short test antenna which is on my bench, about 7 feet of wire. I tuned across each band and could actually hears some stations, especially on band C, the high shortwave band. The volume control was VERY stiff and scratchy, so I turned things off and cleaned it with some spray cleaner and lubricated the shaft with my usual half Marvel Mystery Oil and half 10W30 I use for gun oil. After working it back and forth a few dozen times it freed up nicely. Tried the radio again, and the volume control works very smooth and no scratching. I can hardly wait until tonight when I can give her a little better test. I guess I didn't screw things up TOO bad if it's working this well already.
