2 Devry Corp IC QAF-1D Vintage Rare Mono Audio Tube Amplifiers with mic preamps. Killer working amazing sounding military bulletproof theatre amplifiers. Outstanding Thordarson iron. I have been currently using them in my stereo system. Connectors will be included. Only two wires have been changed to allow noise free line level input. Easiky reversible. One of the first best sounding pair of amplifiers I have owned. They are a pair that are basically the same made one year apart. Slight differences in thordarson transformer construction due to them being made a year apart. One case is green. One is gray. They will be shipped in their indestructible cases. Really incredibly well built versitile amplifiers. Maybe the finest killer amps I've had the pleasure of owning. Included are power cords that work to test and use my tech constructed because we do not have the original power cord connector and did not want to alter them. XLR to rca adapters included as well. Comes with tubes that are in them free. Ready to play and enjoy!
