The classic dual complex oscillator from Buchla, now available in eurorack format from Tip Top Audio!  A must have for anyone with a 200t system.

The 259t features two independent oscillators - A modulation oscillator with selectable waveforms and the ability to go to LFO range, and a principal oscillator featuring sine, square, and wavefolder outputs.  An integrated wavefolder shapes the sound of the principal oscillator, as well as phase lock/sync input and modulation from an internal bus.  The internal bus has switches to send the modulation oscillator to modulate the principal oscillator's pitch, amplitude, or wavefolder drive. and is designed to be modulated at audio rate - between the FM AM and wavefolder tones, a huge range of sounds can be produced by these oscillators!  Modulation oscillator also includes a unipolar output suited for CV modulation and both oscillators can be tuned by an auto-tuning system, either on their own or with help from the Tip Top audio ART line of modules.
