Rogue MegaWatt 30Amp bulk charger.
Been using my Megawatt 30 amp PSU now for over a year with the fine adjust pot, when mxwanderer suggested a 500 ohm 2 watt 10 screw potientiometer to replace the rather touchy one screw micro pot. ...

Nice clean job!
Just hope the electrical signal is as clean. The pot is connected to the error amp within the PS. This is the most sensitive portion of the PS. Any noise introduced to the input of the amp (from the long pot cable) can be increased by a million from the error amp.
It's a good idea to hook up a scope (perhaps on ac setting) to the output. Any difference in waveform when holding the pot?
