This is a 400-X model completely restored by Paul Grzybek one year ago. It was recently in for a check (I live near Paul) and is ready to go. This is one of the best tubes amps for headphones, and can drive anything from Sennheiser HD's to AKG1000's with ease. This is an all tube receiver, so it also includes an excellent phono stage, tuner, and 28 tubes watts per channel to drive speakers. Also has Aux-In to connect your CD player. It is tubed with Sovteks and the output tubes are EH EL34's. I will include free shipping within the U.S. to any headfier who buys it. Asking $675.
