1)
The filter electrolitic caps in the power supply circuit of my SX-28 (C48 and C49) are connected to GND only by mean of metal clips. As they are not original I don't know how they have to be connected to restore the original layout.
Can somebody owning an SX-28 have a look inside it and confirm how they were originally wired to GND?

2)
My SX-28 is missing C51 and C52. They are connected to the PRIMARY leads of the power transformer, that is directly to the HOT and NEUTRAL leads of the power line input. Question: are they needed? Why? Are they safe? Do I have to reinstall them?
Thanks alot
