I still have a AM/FM/CB factory Delco radio (no tape player in it though) from a 78 Caddy I had in one of my 70's Pickups,still works OK,but one channel died ,so it plays in Mono,not stereo ...probably needs one output transistor to make both channels work again.................................................................................................I have a bunch of aftermarket take-outs I bought over the years that have the dual shafts,like a Blapunk "Denver" Am/FM cassette,and various others like Audiovox ,Jensen,etc...-have been sitting for years in my garage along with multiple old school graphic equalizer/amps and other 70's and 80's vintage "stuff"...not sure how good they work now,they were pulled in favor of later CD style units..dont know why I even keep them anymore,probably couldn't get 5 bucks for any of them at the flea market/swap meets!...................................................................................................I may even have a AM/FM 8 track in my collection still,I took a whole store display "wall" of radios one of the parts stores I worked at that they were going to chuck into a dumpster,and I sold almost all of the 8-tracks in a matter of hours at a swap meet many years ago!--I wouldn't have junked those,a lot of classic car owners now want to get one to keep their cars factory looking...got quite a few old CB's too,some 23 and 40 channel and some smaller ones with only 3 channels that still worked too....
