Preamp cutting out on left side

My Manley Jumbo Shrimp pre amp is cutting in & out on the left side only . Opened up to look for cold solder joint , don't see anything obvious ....poked all the joints with wood stick...seems to cut in & out when I mess with the middle circuit board and the back plate of the box? Any ideas ?

The reseating of all the tubes has seemingly solved the issue “for now”…it’s been 2 weeks and no cut outs , I’ll report back after more time passes , thanks for the help .

just to put a period on this problem ...it was the selector switch of my Manley Jumbo Shrimp Preamp that went bad and was causing a short on left side...replaced , all ok .
