This was a little goodie I picked up at an estate sale about a year ago. It was brand new in the box. The price was right, I bought it. It is more of a curiosity than anything else. The transistors in the kit are gigantic. There are no numbers on the package. I am guessing that they are point contact transistors. They were, my guess, obsolete when the kit was put together and just a good way of getting rid of surplus junk.
Still, the book that comes with the kit is interesting. It goes through the theory of formant synthesis. Plus, it has an experimenters circuit included.
