This amp has a TV front and a 15” Jensen Alnico bluebell speaker with the choke mounted on the side. This example is all original with linen grille cloth and vertical wooden slats hidden underneath the grille cloth to protect the speaker. It has four inputs, two each for the instrument and microphone channels, with two volume controls. The capacitors are original and the preamp tubes are the old metal 6SC7 tubes, which would be replaced in the early ‘50s by the glass 12AX7 – type vacuum tubes.
