[Elecraft] K3 Power Supply

[Lennart Michaëlsson]

Any good ideas?
Presently using an old  (and heavy) Yeasy power supply, working very well
but - like many others I plan to bring my K3 on trips as well.
Anyone tested the MFJ-4125? In that case: How about the noise level?
Any other/better low weight switching power supplies?
Must say the K3 performs very well and has exceeded my expectations.
