The panel was made by Schaffer/Front Panel Express with David's design. The lettering up top is Gabotronics in Bulgarian, in Cyrillic, and the Bulgarian translation for "Oscilloscope" below.

David's hobby, and passion right now is electronic music. Started in about 1975, came to a dead end in the late 70's, and recently picked up again. David is in the process of building a modular analog synthesizer a la Bob Moog's style from the 60's and 70's. David wanted a small scope he could mount in the racks next to the voltage controlled oscillators, filters, amplifiers, etc. to get a look at the waveforms while listening to them.
