A legendary amp with plenty of power for any size gig. This particular example has all original transformers, 1 original speaker, 2x CTS Alnico speakers, and 1 Jensen concert. The electrolytic caps have been changed, along with 3 of the original astron coupling caps, and some power resistors. Some grid stopper resistors were added to the power tubes, and a bright cap was added to the volume pot. Otherwise, all of the original Allen-Bradley preamp resistors are still in tact.
