As noted elsewhere, I identify the radios I have by the order in which I acquired them.
This page is about trying to make the 7th one actually run again. This is the
last acquired of all the radios.
I say 'blog' because it turned out to be a list of what I did, not what you're supposed
to do. If you're bored, you might find it interesting.
See here for info on the original radios.
The 7th radio was sold as restored and fully functional. It included an originial speaker cabinet. It
had been recapped. It worked sort of. It even came with an embroidered cover for it.
The following pages address the things I discovered in more or less the order I took.
While comparing circuitry to the 5th radio, I discovered that SW8-14 was wired completely wrong and that the wafer had been installed backwards.
While playing with oscilloscopes and signal generators, I discovered that it may have been recapped but it certainly wasn't aligned. This is actually a good thing because now I have two radios to use for the development of the align procedure.
