Ameritron ALS-600 Amplifier: Ameritron ALS-600 Amplifier. Rated 160-15M, 600 watts PEP, 400 watts CW. I do not believe this one has the 12-10M modification, but have not opened it to check (the AUX position is silent on receive, indicating that the mod has not been installed). Amp works and and appears to be operational, but sold as is. $975 net to me, pick-up only in St. Louis, MO at this time. Very heavy and expensive to ship.

Nice Ameritron AL-811 $600: Great condition! This is one of the newer models with the highly desired updates from Ameritron (i.e. LED lights, Sealed RF Relays, etc).

If you stop by my shack I would be happy to show you how it works! $600 - No trades please. My contact info is all good on QRZ!
