[Elecraft] PS Comparison: Powerwerz SS-30DV vs. MFJ-4230MVP

[krug261 at yahoo.com]

Greetings all,
I am in the market for a compact power supply. The fact that Elecraft suggests/sells a third-party unit (SS-30DV) provides an automatic sense of comfort. However, always trying to complicate life I was also looking at the MFJ-4230MVP. Same dimensions, weight, power connections. I do like the variable voltage control on the MFJ. Not sure why I would need it, but seems useful.
I doubt if anyone has BOTH units, but even your impressions of either of them would be very helpful.
Thanks and 73, Bob KA2TQVKX3 #9842
