http://Hey all, i'm currently working on a 335 eq, and am having a little difficulty reading some of the values in the posted schematics. I wanted to post these to see if i'm reading things correctly. tried looking in the archives, but couldn't find any clarification.

original:
R1  27K
R2  27K
R3  10K
R4  10K
R5  10K LIN
R6  10K LIN
R7  10K LIN
R8  1.8K
R9  1.3K
R10  680R
R11  47R
R12  3.9K
R13  10K
R14  10K

C1  100uf/16V
C2  100uf/16V
C3  180pf
C4  180pf
C5  500uf/6v
C6  47uf/10V
C7  .033uf
C8  .039uf
C9  5uf/16v

According to my calculations, shouldn't the low freq cap be .47uf for a freq of 232?

Many thanks...

Its 47uf for 23Hz.  The low shelf is actually a bell at 23Hz.
