Your 422 amp: Did you notice a reduction in current for 422's compared with 2879's?
That was why I went to 28v w/ Palomar 900HD. When amp new, it wanted more current than my 40A PSU had. I have no measurements but PSU no longer strains. What are you using for 28v PS?

Ohm's law does apply here. I have not used this amp in almost 30 years, however I still have it and plan to make some changes and use it. The current plan, is 6 MeanWell 28V 6.5A SMPS's in parallel. The old plan was 4 parallel Glenayre 26V 14A SMPS, removed from paging transmitters.

I need to know whether the Yaesu FT990 can easily be hooked up to an acom 1010 amplifier. What is the proceedure?

Tin Can, Alabama Buckeye here. PowerMax PM4-100 V PM3-100? I've a PM3-75 which does not have neither switch nor voltage set screw. Is that the same on your PM3-100?

Hey Alabama Buckeye, I just went to radio room to confirm, both PM3-100 and PM4-100 have voltage adjustment 13v-16.5v and switch that selects 3stage and fixed output. Hop that helps you out, I run both in tandem at 14.5v to run all my amps and radios. fans have come on once since I have owned them.

I'm interested to know why 14.5V?

I adjust my 200A power supply to 14.5V. Stryker 655 or 955 either will readout 13.7V draw. I presume a protection component in the werx

Might I guesstimate 14.5V for the benefit of greater watt output from linear amps? What boost might that be, 80W?

Lately this new guy Rob AKA Skybanger has been making a lot of waves. He's made a lot of people mad.
