Adding Bluetooth to AA5 radio
My neighbor asked me if I could add Bluetooth to her AA5 vintage clock radio. I choked and said I would think about it. Help me think.
My first thought is to not bother with Bluetooth and just add a 1/8" connector to the back so a phone/MP3 player could be used. Add an outboard Bluetooth receiver via the same connector if they cannot live without Bluetooth. Now the problem. Where is a safe place to add the 1/8" shunt to a hot chassis via a SPDT switch? I want to do this as simply as possible without looking for Sams for a location to insert. Somewhere ahead of the amp is obvious. The hi/low sides of the volume control is my first guess. Variations in volume from different sources is to be expected. Can this be done safely?
