RCA mono phono equalizer solid state system with UTC/Kenyon input/output transformer. I have the impression that vocals and acoustic instruments are plump and have a strong presence in the warm mid-range typical of RCA. The left knob switches input, and the right knob switches NORM, HIGHS, and ROLL OFF from above. You can see a feeling of use on the exterior, torn power cable, dullness, abrasions, etc. (Kobayashi Hitoshi)
