Pride of Worksmanship

Every technician, and of course that includes part 15 people, has proud moments when a technical puzzle is solved and everything works.

Today I dusted and opened for surgery a Panasonic AM FM Tuner from the 1980s, Model RE-7680, last used in the mid-1990s. It probably puts out about 10Watts per channel to external speakers.
Back then I had carefully re-wired the audio section so it would interface with a special speaker system at the time, but now the application is different and I needed to return it to original condition, but was not sure where to find my notes showing the changes. So I began a forensic investigation.
By noting clues such as “wiring I added” vs. “original wiring I had tapped into” I was able to reverse-engineer and get back to the original state.
Now the tuner works perfectly.
What is it for? Aha, it’s for the carrier current project, and the amplifier discussion will continue in the Carrier Current Journal.
What was your latest technical achievement?
