    ICOM no longer sells the PS-126, so I was hoping that someone could give me a suggestion for a power supply for the ICOM 7610.

    Here's the specification in the manual ....
    When using a non-Icom DC power supply, you need:
    • 13.8 V DC (Capacity: At least 23 A)
    • A power supply with an over current protective line and low voltage fluctuation or ripple.

    I use one of these

    to charge an AGM battery and power a strip.

    This works very well.

    You don't need an Icom power supply to power your radio.
    An Astron RS 35 will work. You can even use an Astron switching power supply.
    Call Ham Radio Outlet for other suggestions. Just don't get a cheap power supply off of Ebay.

    I also vote for the ASTRON RS-35. Just remember it is rated 35 Amperes PEAK, but only 25 Amperes continuous. If you have other radios, or a lot of accessories, you may want to upgrade to a higher capacity Astron. Linear supplies ARE heavy, but mostly rock solid, and repair is possible IF ever needed. My RS-35A has been in service with nary a hiccup, and no time off, save for power outrages, and the infrequent vacation of a week or more, since 1990. There is no need to buy an Icom supply; you are paying more for the name than for the "innards."

    Thanks for all of your suggestions. I ended up going overkill and purchased the Astron RS-50M
    Linear, Regulated, Dual Meter(backlit), 50 A at 13.8 Vdc Peak Output, 120 Vac Input.

    Hopefully that will meet any other needs as I add equipment to the shack.

    Moving on to the next step... I am eyeballing the RIGRunner 8012 from WestMountain Radio. Is this a wise choice?

    The Astron will serve you well for a long time.

    The RIGRunner is a fine power distribution system. The only complaint I have about it is the price. You may be able to home brew something equally effective for less cost. Consider that you may only need one or two high-current transmitter circuits, which can be directly wired to the Astron's terminals with heavy gauge wire. One more, smaller, fused circuit might provide power to several lower powered accessories.

    But the RIGRunner should do the job very well.

    Good choice on the power supply. You will have extra capacity for expansion, and the 50 Ampere supply will simply loaf with your current requirements.

    Run the IC 7610's power cord directly to the lugs on the back of the power supply. For other accessories in the shack, a Rig Runner will do just fine.
    I run my TS 480 SAT and my TM D700A directly to my Astron RS 35 and I use the MFJ-1126 to power everything else in the station.

    By the way, I've been using my RS 35 for almost 35 years and it's still going.

    I bought a RS-50M just a few years ago. I noticed it got quite hot even with no load. Called Astron and they informed me they received a bad batch of transformers from Federal. They sent me a new one that was very poorly packaged. After I got the bent brackets straightened out I mounted it and soldered the wires to the windings. A 140W Weller Gun barely made enough heat for the job. Power supply works great now.

    You can't go wrong with an Astron though. Lots of folks love their switchers but I wonder what they would say if they actually saw the waveform from them.

    You need a 13.7v supply with at least 23 amps , over current protection and low voltage fluctuaton or ripple.
