PROBLEM SOLVED !!
Today I opened up the unit. removed the connections to the board that has all the control pots. then took a can of D5 De-oxit and sprayed all the contacts of the connectors, and sprayed into every pot as well. turned the pots back and forth a dozen times to work the deoxit in well to clean the pot's wipers, put the connectors back on and tested. the crackling went away !!! put the unit back together and put it back in the rack case. Ready to rock once again!Go to the full post
