CHORUS Crackle

2013-12-10 by Gregory Thomas

I love my EX-800, however I notice when I have the Chorus on, and ONLY when I have the Chorus on (parameter 48 turned to 1), it ";crackles" when the cutoff (parameter 41) is above lets say 32 and is introducing additional harmonic content. This is not just the L+R output, but it comes out of the Phones. It's not the signal coming in hot, because I can have the Volume know at 1/8, and as long as the Chorus is on, that crackling is produced. The moment I turn it off, the crackling is not introduced into the audio, again, regardless of where the Volume is set. I have no problems with any static coming from my knobs, and quite honestly, I got this unit second from someone who bought this new in 1984 and used it seldom and it is in brand new condition (at least cosmetically.)
Is this a characteristic of the KLM-598 Chorus chip? Or rather, is it that my chip is just so old it needs to be replaced? Thoughts?

Thanks!

Greg
