Used XPA125b: While the tuner is awesome, the amp side is somewhat finicky with my x6100. I did upgrade the firmware. But this setup isn't the best fit for my go-bag. I'm including a power cable & the firmware upgrade cable I bought separately. Depending on the rig you're connecting to, I also have both the RBI-1A & L4001 connector options as well. We can work that out if you need one.
Asking $450, lower 48 only. I tend to ship USPS Ground Advantage. Paypal F&F preferred.; Listing #1755362 - Submitted on 01/10/26 by Callsign N7JFB - IP: 65.182.231.228; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
