Several years ago, I constructed several of these devices which employed only four transistors, resistors, caps, and diodes. The design looked terrible on paper. ( the horizontal sync pulse was rectified and filtered to provide a DC power supply for the transistors). However, the device performed quite well, was cheap and self-sufficient. I have lost my schematic and thus I don't know exactly how the signal matrixing was done. Does anyone recall this circuit? Any help will be greatly appreciated.
