hi may be far cheaper and easier to add a ?3.5 mm stereo jack , but yes a cord to iphone , I pad . I have done this , 5- 6 times use two 10 k resistors to mix the two channels , i added a Spst tiny micro switch to tuning so you tune to 55 and it cuts out radio audio connects the two resistors to volume control input . These radios usually need new electrolytic capacitors , leave old one in plsce but strategically cut foil to it . then add modern panasonic axial capacitors, same uF 16 or 25 v anywhere in radio . Trying to exchange or remove old one destroys the pc card ,,they are very fragile Also a long light spring from L shaped thing in tuning gang to case side adds force so tuning clutch won’t slip .strength is critical , too strong makes buttons hard to push . Last the tube pins get corrosion in sockets , causes intermittents. scrape each pin with razor knife then coat very lightly with silicone grease . ends that issue . above assumes radio is basically ok , tubes are almost never bad , sometimes output transistor , ( article on our tech site) geranium replacements available now again, e bay . occasionally IF transformer goes bad , trying to change them destroys pc card . The radios are getting really old now , pc traces lift off card —-fine wire inside IF trans corrodes. Don’t “ align” or turn anything , they are stuck , especially IF trans you break it —- and seldom if ever needs that anyway … and then nothing to listen to on AM — so : After all this , i sort of stopped doing this , i used chrome nose of an old radio , then used retro sound kit sold for VW , made a black delrin filler , same size as old tuning dial , put 300 knobs on ( they fit!) gets you the jack am/ fm too . . looks better than factory , digital clock too . Can modify jack to be on delrin . lot less hassle works great few hundred $ and a day , put two killer 6x9 speakers in back .Dual voice coil etc are junk in front , waste of time and money Maybe bluetooth stuff now in new retro radios radios too , it has been years since all this just info , one guys track on this .. jg Sent from my iPhone On Jan 12, 2024, at 10:16 PM, 'Matt Allyn' via Chrysler 300 Club International <chrysler-300-club-international@xxxxxxxxxxxxxxxx> wrote:
