Rectoverb 50 combo circuit board flexing problem

[teamcenobite]

does anyone have any experience with issue regarding the flexing of the circuit board at high volumes, which causes intermittent break of the connection to the power amp connector. it doesnt happen at lower volumes, but at higher volumes the vibrations cause the flex.

Here is a picture with arrow pointing to location of flex that is causing the issue:

Do you have that anti vibration grounding screw in place ?

Its there, but it is loose...not sure how tight its supposed to be though, dont want to go too tight.

should be snug I would think. I would tighten it with a screwdriver about 1/8 or 1/4 turn after you feel it makes contact. All your doing is making sure the screw makes good contact with the foil in the combo cavity.
