Recommendation for a Blue Tooth Adapter for a Vintage Stereo

IF you have a PC, with internet, you can stream AM or FM Stereo Radio stations all over the world for free. As well as Pandora free, YouTube music, Amazon Prime ..... 

If your laptop or PC has bluetooth, .... others can tell you about that.

Least costly, but lowest quality, is using a headphone output: 3.5mm jack with a cable that has rca L and R jacks on the other end. They come various lengths

Better, is to use a USB cable out of the PC to usb in of an inexpensive DAC like the one I learned about here:

It comes with a cable, I added this usb extender for my setup, works perfectly

I neglected to point out that there is no WiFi available at my remote cabin. I do however, have a couple of bars on my cell for streaming radio stations, thus my plan is to stream through the vintage console.  I know I could just get a BT speaker and I do have a small JBL BT speaker which is what I have been using.  I am just looking for a bigger sound.

The Wiim should meet your needs, and adding AirPlay might give you better sound than Bluetooth 

I found the answer to my question, which is to go with an adapter with AptX HD technology which has a higher degree of resolution than standard Bluetooth.  There are several devices with RCA outputs in the $40 range.  Thanks to all who responded.
