#142 Theremin

Popular Electronics
Arthur Harrison 1974

Here we have the original circuit diagram, and the same design, but set out in three clearer diagrams (1999 by Arthur Harrison), which are easier to read This used to be a kit from Southwest Technical Products Corp. back in '74, called kit #142, a.k.a. the TECI Hybrid Theremin. It was published in Popular Electronics in that year. The design has some corrections and improvements over the '67 model. This theremin is fairly easy to build, however, placement of the components is a bit critical. Look at Art's Theremin page for more info and construction details.
