Getting back to the Silvertone stereos, I managed to find two more 12AX7 tubes and swapped the 6BQ5's into the middle unit to test it. After swapping out a couple flakey tubes in the AM section, it now fully works as well. Even seems to sound better than the bottom unit in the picture. I have another tube tester on the way that can test these newer tubes, so that will help as the one I have right now doesn't list the later tubes from the 50's and 60's. Might do a case swap between the middle unit and the top 'parts' unit later on.
These are model 7407 tuners and the speakers are model 7438 with Jensen speakers inside the cases. Anyone know what other speakers I can match up with the second working unit once I find more 6BQ5's?
