    Cetron 845 tube front

    Cetron 845

    We were lucky enough to get one piece of very lightly used Cetron 845 built in the 49th week of 1978. It actually tests brand new on our Amplitrex AT-1000 at 97.6mA (97%) and 3.08 gm (102%). The tube has little to no use and has excellent flashing but was placed into equipment at some time. An excellent value at $1199.99 Recommended for Magnetic LM-845, Designs — 845 SE, Mastersound Compact 845, Thomas Mayer amps, Cary CAD-211AE etc Click for 845 specs: 845 data sheet
