[sdiy] Moog-type highpass filter

[Gergo Palatinszky]

Hi,

As a question connected to this design:

If somebody using 2 x NE5532 for the ladder opamps (opamps for CVs and output buffer can be TL... or better);
is there any needs for compensation (extra caps) somewhere ?

Thanx

Br,
	Pala

One of my students is going to try building this:

It looks pretty straightforward.

Any obvious "gotchas" jump out at anyone?

I'm not sure what the 100K to ground at the positive terminal of the "output" op amp on the right is doing...
