My guess is that your 'pd-svn' is actually my 'trunk', so try this:

find ~/pd-svn/ -type f -print0 | xargs -0 grep '"biquad~"'

I find the best way to find the source of an object is to run this in the terminal:

find ~/code/pure-data/trunk -type f -print0 | xargs -0 grep '"biquad~"'

The class name needs to be declared using gensym("biquad~"), so if you search for the object name with double quotes around it, you'll find that gensym statement:

./pd/src/d_filter.c: sigbiquad_class = class_new(gensym("biquad~"), (t_newmethod)sigbiquad_new,
