Eric Picked up an old Fidelity Rad 15 Portable Radio (what a mouthful!) dating from the 60s, I'll post some photos of its insides at some point (it's nice to see "more simple" old school electronics). i.imgur.com/1Xv6oM... i.imgur.com/AlwIuf... I'm hoping to maybe replace the speaker &/or have it accept some form of AUX input, hopefully without wrecking the original functionality too much.

John Olinda I imagine you could wire in a Bluetooth module pretty easily. What type of cells does it use for power?

Eric I could but I'll start with the basics, I'm a electronics noob. It uses a PP9 9V, just ordered a bunch so I'll see if the radio functions fully tomorrow before I start tinkering proper.
