You can replace the j-fet contraption in your schematic with a lamp. Certainly bit antiquated, but much simpler and tends to work better. Pic related.
There's another classic producing simultaneous sine and cosine using two opamps, but it has somewhat higher distortion.

And since it's year 2017, microcontroller might be worth considering.
