My 48-482 project
#30

I knew that FM was not giving me the audio out it should have. I went back over the whole FM area around the FM1000. Found the problem. It was my OWN bonehead mistake. Instead of wiring C 304 to the 6th terminal from the bottom in the diagrams, to the junction with R302 and C305, I had wired it to the 7th terminal. I'm surprised it worked at all. I corrected this mistake; and, while at it, replaced C305 with an 820mmf and a 680mmf mica condenser in parallel to replace the 1500mmf mica condenser. FM was immediately a LOT more powerful in its audio... too powerful by far, and I had to re-tune the Z300. Once that was done, FM is excellent ! Volume on the local stations is now up there with the AM band, and the sound quality is fine too. I am now finally satisfied with the restoration of this radio.
