[sdiy] Final-stage mixer module?

[Dave Brown]

I made a final mixer with an A-440 standard and an output attenuator with DC
blocking capacitor.  I used 47 uF!  Details are on my page
http://modularsynthesis.com/modules/DJB-002/djb002.htm

Later, I added a Fixed Filter bank which makes for a really nice stereo
spread so if I had to do it over again, would do a stereo version.

I'd like to make a simple (TL07x) mixer for the final output of my modular.
I want it to block DC. I recall seeing a schematic that showed two
electrolytics back-to-back to achieve this. Is it as simple as that? Or is
it better to have small ceramics on each input instead?
Both?
