Ok, stupid question time, what exactly is a diamond buffer.
It looks to me at first glance like a way of keeping the power rails balanced like a resistor divider except, it is on the output side? I can find many pages with PCBs and diffirent diamond buffers, but none of them clearly tell me what the hell I should do with one if I built it, what are the limitations? If it does sit on the output side I would imagine power limits... Please connect a few dots... I'm a quick study normaly, I promise... |

I´m curious too!
don´t know exactly what a diamond buffer is, but it maybe referencing to these pushpull-emitter followers, where two emitter followers, one npn - one pnp, symmetrically drive a AB-pushpull output stage. Regards |

On page two of this PDF is a schematic of a diamond buffer:

Like I said, getting a circuit no problem, but what does it do?

Do a google search for Jung Diamond buffer. You will find the source documents by Walter Jung.
