Yamaha m4


I have a yamaha m4 I took the cover off to clean it and when it is on I moved the      2 big  caps when i moved  them        back and four they made poping sound . If dont move them its  fine..is that ok?  thank you.

Doesn’t sound great, does it? Either the caps' connections are intermittent internally or the solder joints to the board are dried out.
