The Crystal Tester Thur-Hole Kit, 9 vdc. This is a teaching kit so your family could have a lot of fun enjoying doing something together. Everything is turning into a trash it and buy a new one with modern day electronics. We need family's to start working together and learning how to repair things when there isn't any Elmors around to teach. Let's face it with the cost of college books, living expenses, how many kids are going to be able to live our old dreams. Think about it talk with your family make it a fun project. You may have a younger person that has the light bulb burning to learn new things.

We as a country need thinking minds to built a new future in our world.

I have been into electronics for 52 years and still enjoy it everyday. I'm always learning how to do things different to make things work. Not from the just making money from it but to keep our minds working so we have people out there that can teach and bring the melting pot of minds together to work as a team.
