1973 Fury III 2dr, AM radio non-working.

[TaffetaMocha]

Was using the radio, and all was well until it cut out. No sound, No static. Listened closely and I could barely hear a station while running at full volume. Tried to locate fuse, but it is not on my wiring diagrams. Can anyone tell me what fuse I should replace? or maybe another solution?

Do your turn signals work? Same fuse. If they work, the fuse is good.

Check the antenna connection.

unfortunately turn signals work and the fuse is good. Antenna connection is good aswell

It may have a bad capacitor. A known failure with old electronics. Who repairs old radios?

There should be either an "accessory" fuse, or "radio" fuse in your fusebox under the dash, next to your left foot.

BUT.... this does not sound like a power issue... this sounds like you blew an old transistor or most likely.. leaking capacitors...so... question.. how good are you with basic electronics and soldering. To me, it sounds like you have some bad/old capacitors... and you can definitely replace them. I had the exact same issue with an old 70's era GE flip-clock radio I bought on eBay. I took it apart and "recapped" it and it works great.

If you can handle this type of work, it's worth a try.. after that.. it's either bring it to some one, buy another and hope it works, then swap whatever parts.. or the most expensive.. but best option... have it converted to a modern interior radio with BT compatibility and AM/FM options. Again... pricey... but they work awesome and look stock. You can't tell.

Who repairs old radios?

Places that repair old radios are few and far between. The places that do are usually some retired electronics tech doing them on his kitchen table. You have to give the secret knock to get in and then hope you get it back.

My suggestion is have the radio updated and be done with it. Not cheap, but it keeps the stock appearance and you end up with a much better radio. There's a couple places, but I always recommend this place. Aurora FMR Stereo Conversion

The Good News is: 1.) These old radios consist of discrete components on circuit boards easily soldered and de-soldered. Are you capable with such tools and work? Replace ALL the capacitors if capable. Then power it up and listen. This is an internal power issue all right.

"Listened closely and I could barely hear a station while running at full volume. "

So, it still tunes, and passes audio, but fails to amplify.

The OTHER likely failure point, with the symptom described would be the 2 transistors, both of them on the outside of the unit, up front near the top. Those old bipolar junction units can burn out over time. If cap replacement doesn't do for you, replace the transistors. Equivalent FETs can be had now fairly cheap, if you fancy those over BJTs. More efficient.

2. An entire radio receiver and player board can easily be installed in that old chassis too. One can add bluetooth.

3. Folks occasionally sell working units. While not so common as Philco or Delco stuff, they're out there.

4. One can buy a modern unit, made for your dash. Pricey but best option if you have $$.
