im trying to do the fm tracking adjustment on my rebuilt 828. no matter what i do i cant seem to adjust the local oscilator L4,below 94 mhz im starting to back the slug out of the coil. the var cap is clean as a whistle and the shaft wipers were deoxited and lubed. im using a panasonic vp-8177 signal generator its ancient but it works. i verified it at 90 and 106mhz on a working pioneer tuner (sx-1500td) i know newbies arent supposed to fool around with tuners but this one was so whacked i figured i didnt have much to lose and do have a spare 828 front end. ive touched NO other adjustments. ive got 3 DIFFERENT pioneer 828 tracking proceedures and im following the proceedure from what i believe to be the latest version that has step 6 "adjust generator and tuning dial to 90 mhz" ..... ive verified that the air cap opens and closes completely and that the pointer covers the entire scale spectrum. i really want to learn how to do this/
