While investigating ways to convert my North American-procured 5153 from "120 VAC" over to 230 VAC, I noticed the design of the internal switching power supply may not actually preclude handling both input voltages. Looking further, I found this quote in the manual on minuszerodegrees.net:
![]()
On the back of my particular unit it states 120 VAC and according to the SAM's manual the EMI filtering near the IEC connector has 120 VAC caps but I see that on a pic I took of the PS board a few years ago that it's additional mains filter uses 250 V caps.
Another concern is the degaussing coil and series PTC.
Has anyone operated their 5153 on both mains voltages and what is the marked specification of that unit?
