Comments: Tremolo: 5G13: 2 x 7025 (harmonic vibrato) 6G13-A: 12AX7, 12AX7 and 7025 (harmonic vibrato) Mode 6G13-A's tremolo circuit left 12AX7 unused. Some early Vibrasonics have a plugged hole in the rear panel labeled "pulse adj." located about 1½" to the right of speaker jack. As the label implies this may have been a control to adjust the waveform of the tremelo. 60 Vibrasonic Rear Panel
