pic 2 is of the radio opened up. the radio runs off 9vdc. it has two battery connectors but both are wired in parallel. now is a good time to see if your radio works at all. do not exceed 9v input to the radio. you risk damaging some VERY hard to find transistors. this radio will power up with 6v-9v. you can use a regulated power supply or a 9v battery and alligator clips.
look at the old battery connectors coming out of the radio. on the connector at the end of the cable, the terminal at the very end (not where the wires come in to the connector) is the positive terminal. apply power, turn the radio on at full volume, and tune around. get anything? any sign of life is good. it's possible your radio may play loud, in that case back down on the volume control.
your radio should have a pictorial diagram inside like the one in pic 3. it may be of help here. on a humorous note, the pictorial diagram shows the transistors in transistor sockets. the actual production model just re-used the tube sockets.
are you getting lots of hash and noise but nothing intelligible? is the radio right next to a computer or lithium battery charger? those two things can generate plenty of RF noise on an AM radio. relocate the radio and try again or shut off the possible noise sources. try again.
get anything now? if your radio picks up anything, that's a good sign. tinny, weak, or distorted audio we can fix. if your radio is totally dead you may need to do some simple checks.
take a multimeter and check for continuity from the positive battery terminal to the metal radio chassis. the radio should be switched on for this test. like many early transistor radios, this one uses positive ground. you should have continuity. if you don't, you need to find out why.
look at the volume control. the power switch is built in. it's got two terminals grouped together. those are the power switch terminals. check for continuity here. you should have continuity when the radio is switched on. if you don't, your power switch is bad and that would cause a dead radio.
if you have a totally dead radio, there is still hope but you may want to consider the fact that your radio may have issues beyond the scope of this instructable.
next up, we get inside.
I remember the days of the mixtape. Requesting songs from the local radio station and sitting by the cassette deck, finger on the record button. I remember the glorious day I got a dual cassette deck so that I could copy music from one tape to the next. Spending hours making mixes for friends, coloring cassettes with permanent markers or nail polish or glitter. Whatever I had lying around that could safely go into the tape deck. They weren't just plastic cassettes filled with noise, they were little works of art. 
To Make A MixDrive You Will Need: 
I was given an odd lot of forks and spoons after my first husband’s parents died. They have been sitting in a drawer for a very long time. Recently I brought them out and contemplated turning them into jewelry, specifically a ring for my right hand and a bracelet (that’s another Instructable). This silverware has silver in it, but it isn’t sterling silver, because real sterling silver is soft enough that a ring could be made with hands alone. No such luck with this stuff. It is much harder than that. So this Instructable is about how I took the handle off a fork and turned that handle into a right hand ring. Here we go.

If you don't have a dedicated yolk separator, separating eggs always runs the risk of a cracked yolk seeping into your egg whites. But if you use three bowls throughout the process, you'll never need to worry.Emma Christensen at The Kitchn, like many of us, used to use two bowls, cracking the egg into one, and scooping the yolk into another. A better solution is to pour the whites from each egg into a third bowl, and keep cracking eggs into the newly emptied one. That way, if a yolk cracks, it will only ruin one egg, instead of all the eggs you cracked before it. It does create a little more to clean up, but that's a small price to pay for perfect egg whites.This is the kind of tip that's obvious in hindsight, but worth keeping in the back of your mind whenever you need to separate eggs for a recipe.Why You Should Use 3 Bowls When Separating Eggs | The Kitchn
