Marshall SL-X Standby Pop
Hi all -  
 
I've got a Marshall model 2100 (JCM 900) SL-X on the bench right now which has a pretty substantial pop when turning the standby switch on or off. Every now and then it won't pop, I suppose when I'm lucky enough to hit the "zero cross" point in the AC waveform at switching.  
 
I have actually disassembled, inspected, and cleaned the contacts in the switch so don't feel it is the culprit.  
 
Is this a normal thing for these models?  
 
Anyone successfully cured this problem with an MOV or cap across the switch terminals?  
 
Thanks - Mark
