You say that like its a bad thing ;) But yes.

Looking at the scope traces from that guys site (which I will read later
today), there is some fairly serious HP filtering going on sometime after
one of the amp stages. Its not that suprising, it seems to be one of the
things that gives 303's there distinctive bite, and might play well with
further waveshaping stages.
