Dual Oscillator Model 258t

Welcome to the Buchla & Tiptop Audio 200 series project. In this project Buchla has teamed up with Tiptop Audio to resume the production of Don Buchla’s 200 series and convert it to Eurorack standards. These extremely rare pieces of equipment made almost half a century ago will once again be available, and this time to a wide audience. Each module will be produced separately as production schedules and component availability allows. We recommend signing up for the project newsletter to get news updates on the progress of the projects and news alert when individual modules become available. Please also join the project’s user group on Facebook to receive all news and more.

Two independent voltage-controlled oscillators.
Each has one processing input, a frequency modulation input and a 1V/oct input. Waveshapes, as well as frequency, can be voltage controlled. Model 258 oscillators feature low sine wave harmonic content, negligible settling error, and high short and long-term stability, even with rapidly changing ambient temperatures.

TRIMMERS:
There are three trimmers for each oscillator on the back of the module:
1V/oct is the octave tracking trimmer and is set at the factory using high precision instruments.
SHAPE is the trimmer that set the sine wave, for the lower harmonic content of the sine wave.
VC WAVE SHAPE sets the response of the waveshaper to the incoming control voltage. Both SHAPE and VC WAVE SHAPE trimmers are used to adjust the sine wave purity.

Condition: New
