I would open it up and spray it into the pots and switches while working them back and forth gently. That may clear up the problem. While you are in there take a look at the capacitors, visually inspect them. You may want to replace the caps on an older unit. Look, that would be very helpful. There is a site called electrotanya. Quote Not to worry. There are very few adjustments on the amp — these are monoblocks — and as I mentioned, I isolated the input circuit where the level adjustment is from the power amp and the popping continued at the output; so the popping is definitively occurring in the power amplifier circuitry. Pretty sure Marantz would know, but getting answers from them is like pulling teeth. Sucks, I have one that pops like what you said. Would love to hear from anyone out there what to do. Mine has a faint burnt smell but could not notice where the burn is coming from. Quote When the amp pops, handleiding marantz ma 500 capacitor life green light blinks and then reboots itself like when you switch the amp on. Does you amp has this symptom? Quote Well, mine seems like an overload problem as it clips and pops then reboots. Hope someone out there has an answer for this. Quote My 7 mono blocs are 11 years old, and 5 are crackling and popping. I had the MA running again by replacing the transistors on the power am pc board. If you have the manual, its on page 8, look for A 4 pcs and C 2 pcs. Now the popping stops and its singing again. Hope you guys find this helping. Quote Thanks for the post.
