If folks are genuinely intetested I could assemble a how-to-do-it article about setting up a Megawatt for Dummies. But not if three days of hard work does not become a "sticky". Don't care if it has my name posted. Something to be mounted in a compartment. Yes, it means running power to the compartment even an extension cord. Complete with German Hunting Handbook grade instructions...and genuine pictures.

I for one would love a "how-to-do-it article about setting up a Megawatt for Dummies." But have no idea how to go about requesting getting it made into a sticky.

The tiny voltage trim pot on these switching power supplies is rated for a rotational life of only 50 cycles.

Perhaps not an issue for someone who sets it to 14.x and spins the spring wound timer and has no need for a different voltage.

Removing this trim pot and replacing it with wires leading to a higher rotational cycle life more precise potentiometer is hardly rocket science, but does require some soldering skills AND or Disassembly of the unit, whose transistors use the casing as a heatsink, and require reapplication of thermal grease on reassembly.

At maximum output( think depleted battery) they get hot and should employ additional heat removal methods beyond the little sleeve bearing 60mm fan provided with the unit.
