This is a great value blackface era Super Reverb, with original transformers. The baffle board and speakers have been replaced, which is why the grillcloth looks different than typical Supers. Circuit-wise the power cord and electrolytic caps have been changed, along with a handful of resistors swapped for proper spec carbon comp types. The reverb tank, bag, and cables have been replaced as well. All of the original "blue molded" Ajax coupling caps are still present, so the true blackface sound is still well in tact.
