Single transistor phase shifter

  
This circuit provides a simple means of obtaining phase shifts between zero and 170°. The transistor operates as a phase splitter, the output at point A being 180° out of phase with the input. Point B is in phase with the input phase. Adjusting Rl provides the sum of various proportions of these and hence a continuously variable phase shift is provided

The circuit operates well in the 600 Hz to 4 kHz range.
