$10 for both. The Radio Shack is 8W, I need help converting. I'll take inside pictures and post tomorrow because I really like the sound of the lo-fi

The comments below are more relative to the Radio Shack unit. The Panasonic radio may need a different approach. Perhaps tap into one of the UHF TV switch settings?
Look in the group "Old Radio Amplifiers" for my conversion photos titled "1964 Philips Radio Conversion". Photos and description will detail the steps I used.
Easiest method is to locate the source signal (radio tuner) and intercept the wire that goes from the tuner potentiometer to the volume-on/off pot. You may need to remove the battery compartment to find the wire, but the extra space will help while converting. Just replace the battery compartment as the last step.
If you want the radio to continue functioning, cut the wire mentioned, connect the radio tuner side of the wire to one of the outer lugs of a SPDT switch (on-on). Connect the volume-on/off side of the wire to the middle lug of the switch. Then add a 1/4" input jack (tip + to the other outer lug of the switch, and ground to amp chassis).
