Emitter follower differ GND potential

Jerry Norris · 2011-06-10T01:16:36+00:00

I have generated a 20Hz sinewave at 5Vpp. The circuit runs on 6Vbattery power with a normal earth reference at 0V. To obtain higher current, I would like to feed this into a darlingtonemitter follower that has +12V and +6V rails. Yes, I do need it thatway.In terms of circuitry, how do I deal with the lack of a common"ground" potential?Jerry Norris

Your diagram is deficient in describing your intentions, I think. The amp is only using 12V, so the other two batteries are extraneous.

You are no doubt right about that, Fred. I will try both ways to learn more about it.

Thanks for your help.
