Two monoblocks based on the 211 tube. they have 2x211in each block, 2 driver el34 tubes, and 4 input tubes 12at7. I have changed all tubes to NOS 211 GE, el34 JJ, and 12at7 to NOS Telefunken and Mullard. These amps are for 230v, and output about 180watts in class AB. You can change impedance between 4 and 8 ohms. They also have a switch for low and high negative impedance. I have had those for about 3 years but after selling my big speakers, I have to sell those as well. I have the original boxes.
