"Today's project was a broken 259. The modulation oscillator was not putting out anything in the sawtooth position of the switch. The Harmonics Order control was doing nothing, but voltage was effecting it. Judging simply from the outside of this module, I can assume it was not built at the Buchla factory, but was a kit purchased at the garage sale a few years ago. The blue LEDs (yuck!) and the black big knobs were the first tip off."

Be sure to announce your garage sale at a free online garage sale. They have some electronics in some of the online garage sales.
