For  proper  operation  of  the  unit,  it  is  advisable  to  use  modules  in  good 

conditions  and  with  coupling  capacitors  that  will  have  been  replaced  if 

necessary. 

The  poor  condition  of  the  capacitors  can  greatly  affect  the  sound  quality  or 

even  cut  the  signal.  Similary,  one  will  ensure  that  the  various  switches  have  been 

cleaned using a contact cleaner spray.
