Ok...Now I'm looking at my moog_hp. (adjust glasses)
I am just guessing! ! <- standard disclaimer!!
I have no idea what I'm talking about here! <- extra protection!!
When I say move I mean re-bias <- jic
There is no real current flow, just a small push/pull action.
(I measured it. Less than 0.1ma min/max cutoff) the minuet voltage
change moves the signal path more pos/neg from 0v. This offset
between the buffer amps/caps forms the filter.
I didn't attempt to match anything ( I hardly ever do...I'm so lazy).
