Ameritron ALS-600. Solid state amplifier 600watt output. No tune and no warm up. Has the good power supply heavy as heck. The face on the supply is puffed out around the edges for some reason but sure performs great and I hooked it up last night and it sure is quiet and so simple to use. I may keep it if I keep testing it. Very compact and easy to fit in on a desktop. Will add pictures from phone later and available on request
