Solid state Ameritron amps, such as the ALS 500/600/1300 require the AMR-Mod-10 which easily installs in the amplifier. There are several versions available for use based on the model and serial number. Please Contact Us to make sure you choose the right one.
For tube amplifiers, we provide an instruction sheet from Ameritron, which gives step by step instructions for the simple modification, which doesn't require soldering. 10/12 meter mods require proof of a valid Amateur Radio license.
