Jen-B,

The attached schematic drawing shows channel 1 of the stereo preamp. The voltage regulators and rectifiers are shared by both channels.

If you draw a horizontal line across the schematic, the lower portion resembles a mirror image of the upper.

Other designers might called it complementary mirror because n (or p) is complimented by p (or n) in the other half.

I called it mirror for simplicity.
