Carvin X60 combo - noisy pots

[StephenGiles]

I have a Carvin X60 combo amp which has noisy pots. I am aware that the solution lies in lubricating the pots, but the chassis must be removed in order to do this. Does anyone have a service manual which might provide instructions for this procedure?

Remove the rear panel and the four upper screws that hold the chassis. I think there is no more.

Many thanks, I'm a bit concerned about damaging the valves but if I can borrow a powered screwdriver, I'll give it a go.
