I know this is very old thread, but I am looking for help before I give up. I found a working Philco 40-120 and I purchased a kit to add bluetooth to it. I was a tech nearly 40 years ago repairing calculators so I thought I could do this . I am clearly in over my head and can't even figure out how to pull the volume Potentiometer out, it appearst to have several wires stiffly soldered to it. What might be the best site for me to view the scehematic and possibly photos to help with this old guy figure it out?
