I'm currently redoing a 939 that kind of does the same thing ..it makes a sharp click/pop occasionally. I got it for a great deal and it is in immaculate condition so I want to keep it and rebuild it. I knew about this issue and the funny thing is after it sat for a while since the previous owner didnt use it..it never made any noises until i used it for 2-3 days. I will keep you updated when i trace down that pesky lil bugger just to see where in the preamp chain it is coming from...that is if i can catch it in the act.
