I have a pair of T.E. Linear B, class A, 55 watt mono-block amplifiers for sale. Recently retubed with matched Electo-Harmonix Gold Lion EL-84s. Amps produce an astounding 150 db of dynamic range with a extremly flat impedance curve. I am the second owner and the amplifiers have always preformed flawlessly. Condition is a very conservative 7/10 based primarily on a ding on one the front of one of the chassis as seen in pics. Amps will be packed in original shipping creates with adequate padding.
