Radio options

Next, take out the on/off/volume rheostat knpb assembly. You will.see r small tabs that hold the front and rear parts together. Carefully pry the tabs out, one needs to be heated to release the solder, and pull the two halves apart.

This is the bluetooth Amp I bought off Amazon for $18. You can see the slot in the Amp shaft. Now lightly file the round part of the half circle shaft coming out of the factory on/off/volume rheostat to fit the slot in the Amp volume shaft.

The Amp comes with a power cord. I then wired a 4 wire connector, similar to a trailer plug, to the speaker outputs.

Then fasten the amp to the radio casing. This was the worst part, trying to get the shafts to line up without binding. I ended up making about a 3/16" wood shim to go between the outer case and the Amp. Then made a 3/4" sheetmetal strap to fasten it to the case.

Then just put the upper and lower casings back on and wire it in. I did cut out part of the back of the casing for the wires to exit.

Overall, I think it took me about 4 hours of tinkering and a total investment of about $25.

Obviously, the am radio no longer works, but the original buttons and scrolling tuning knob do still function. And the original on/off/volume knob works as the original, but now controlls the bluetooth.
