[QUOTE="eedude, post: 82406, member: 2549"] okay perhaps a bad tube. Swap what you can and see. Have you tried removing the module and power the amp on to see if it still makes pops? Do you have a second module to try? It's hard to diagnose remotely, but I did experienced pops in one of my Rm100's. The failure was "arc over" in the power amp section. Arc over is when the high voltage B+ arcs to ground in the amp. When the discharged occurs you get a pop out the speaker (at least I did). I was getting several pops per second. Others have experienced this arc over issue in the amp and on modules as well. I don't know if that is your amp's defect, but it's worth considering. If the the arcing is occurring inside the amp (versus on the module) what you can do is remove the amp from the box. Set the amp so that you are looking at the guts. Connect it all up and power it on. IF the room is dim enough you should be able to see the discharges.... [/QUOTE]
