I found this CCS in MJ's V4. Seems to be an elegant solution if it will work. Once the sides are matched the totem BJT's share LEDs along with any voltage change.
Maybe at some point the CCS folks will chime in.
Anyone have any thoughts on the Zener protection?or other thoughts?
I'm curious about using bandgaps for D6 and D5, like the lm385. I'm not sure I hear a difference with cheap LEDs. But Melrin B claims measurements are better across the Audible frequency spectrum.
