Ameritron ALS-600 (160m-10m): This listing includes:
- Ameritron ALS-600 (newer version)
- Ameritron ALS-600SPS power supply
- Ameritron ARI-500 Band Decoder
- Cables for decoder to amp connection (network cables)
The amp is the newer model and has the 10/12-meter add-on board installed. It also comes with the ARI-500 band decoder. All working as it should and producing the expected output. With the band decoder you don't need to manually switch bands on the amp. I have a nicely printed copy of the manual (not the original) for the amp and the original manual for the ARI-500.
I'm asking $1,200 for everything. Shipping is at the buyer's expense.
I'd also consider a trade for a Yaesu FTDX-10 in like new condition.
I prefer local pickup in the Clearwater Florida area as this would be heavy/expensive to ship.; Listing #1756383 - Submitted on 01/20/26 by Callsign N4WHT, Modified on 01/21/26 - IP: syn-035-140-113-054.res.spectrum.com; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
