Problems with Polysix - may be battery related.

Problems with Polysix - may be battery related.

2011-12-11 by Kenneth

Dear group. 

I have a nice Polysix with a quiet annoying problem. 

Whenever I turn it off its sound is bad. Kind of sounds like a fast LFO is modulating the pitch/volume. 

No matter which knobs I turn the modulation is the same. 

If I leave the unit on for 4-5 hours it sounds good again - and no more problems. 

I can conclude that when the unit is cold the problem is there - when it's warmed up it's not.

The PSU has been checked by a tech and turned out fine.

The battery has been changed for a CR2032, but not all traces on the print seems perfect to my eyes.

Anyone with any ideas as to ehat to look for ?

Best;

Kenneth.
