It would be too bad if the HA-70c walkie talkies never worked again, so let's fix them.

 
The idea was to replace the four electrolytic capacitors, then go after the transistors, which is exactly what was done.
But first I eyeballed the circuit boards, and I found something weird on the first one I opened.
 
WHAT THE DICKENS?! What happened to this resistor? It will be the first thing replaced.
 

The other side of the circuit board has an amazing amount of solder on it.
The manufacturing process was probably all done by hand, and very quickly.
 

The broken resistor, four capacitors and a transistor were replaced. This unit now works as well as it ever did.

 
 
In the second unit there was a wire that wasn't soldered to the volume control. It was just sitting on it.
The catalog stated, "Completely Wired With Volume Control". Wouldn't that imply "Completely Soldered"?

Some of the old capacitors are only rated at six volts! Time marches on - the new ones are rated at 50 volts,
but are the same size. On the right, a 30 MFD cap tests at 728 picofarads. That's .000728 MFD. It is deceased.

 
Soldering the green wire onto the volume control and replacing the capacitors brought the second unit back to life.
Not only do the two HA70C's talk to each other, they are (unsurprisingly) compatible with the HA70d version.

I entertained the idea of replacing every resistor, capacitor and transistor in one of the HA-70C walkie-talkies. Considering how cheaply they were made I'd have the finest one on Earth, but what good would it do me? Who would I talk to?


Now it's time for me to go into orbit around the moon in a Gemini space capsule and talk on my Space Commander. If you don't hear back from me, that pesky heat shield failed on the way home.

This broadcast is now concluded. Tune in again tomorrow; same time, same channel.
