I have a stack ( 4 off ) PM3055 Philips/Fluke abominations. All four have faulty power supplies.
I think the power supply is more complicated than the scope itself ( almost ).
They worked when I bought them, all for about a week ( Ex RAAF training school CRO's ).
They were PSU noisy in that they all have switchmode hash on the trace regardless of what sensitivity the unit was set to.
I am NOT a fan of them at all. The best thing about them was I paid $40 each. Now I need a boat!! cause I have the anchors.
