Marshall SLP reissue 100w

[glasstone]

Hey

I have an Marshall SLP reissue, I have changed the main trafo, the old one was fried, all filter caps are changed. All the tubes are new, bias proper ajusted.

But i has a static rattle, when itīs on, with or without a guitar.

I have removed the bright cap, checked alt solder joints, grounding checked.

Has anyone an idea of what could be the problem?

Do ANY of the controls have ANY effect on the noise? If so, what?

When I turn the controls itīs still there. Itīs a hard one /

Not real sure but having a new transformer, maybe you got a loose one. Transformers can rattle and buzz if they are not tight as a drum or have some voids in their potting. Try torquing down on the transformer mounts, tap it, wiggle it, squeeze it and see if you have any change.

OK, so the controls have zero effect? None of them affect the amount of noise or its tone? Then with ALL the controls at ZERO, the noise remains?

If so, then the power ampo has the noise. So pull the phase inverter tube. Does the noise remain?
