Buzz from CZ-1000 headphone jack ?

Buzz from CZ-1000 headphone jack ?

2007-11-20 by polyone28

hey all- i recently bought a CZ-1000 fairly cheap, but it seems there 
is a constant hum/buzz from the headphone jack. The hum stays at the 
same level with the Vol high or low. The output jack is clean and 
sounds great, and every thing else works perfect. Just wondering if 
this is a common problem and an easy fix--worth taking the unit apart.
 Or should i just leave it be and live with it??
   I'd rather not have to run the output line through a mixer into 
phones(late night sessions) every single time i want to write. And 
believe me,after an hour of dealing with that buzz in the phones my 
brain starts melting out my nose!!
  Any help would surely be appreciated.  -Thanks!!!
                                                   -cb

Are you using batteries?  Cheap wall adapters that aren't well-filtered may cause a buzz on the output- it's not necessarily the CZ's fault.

I had the same symptoms in another headphone output, it was a shot condenser in the 
output line. You need to open the synth and take a look, find the Output condenser of the
headphone line and try to change it with one same vale.
