Hey guys,
Miller Effect has got me down... <commence blues riff>
I have isolated high frequency rolloff at higher gain to the attenuator between gain stages. However, adding a WCF as a buffer after the first gain stage eliminates this, and allows for a lower value attenuator.
This has been confirmed by building the circuit and running sweeps. Miller is a non-issue.
Is adding this additional 12BH7 overkill? That's gonna be a lot more heater current draw and real estate. Is there a better way to buffer between stages to lower impedance and prevent Miller rolloff?
