I have:
Manson ~3-15v 40amp switcher, which currently just runs some LED lighting outside.
Powerwerx SS-30DV, which definitely has RF hash on it (i hope to resolve this, as it's a good compact supply otherwise), but is just manageable and runs my FT-991
Powerwerx SPS-30DM, which also has RF hash on it, and again, hope to resolve, as it's a decent variable.
Not powering any rigs currently is a small lab supply, a Trio PR653, but also needs some work for reliability (has a sticky relay i think).
Plan at this stage is to build a 25-30 amp linear, but want it to be as safe, reliable and well designed as possible... Watch this space?
