It was usually a 12AT7, for the same reasons as the reverb driver above. This tube offers low noise, low microphonics, and warm smooth tones at a great price. All AB763-similar circuits (Deluxe Reverb, Super Reverb, Pro Reverb, Twin Reverb, Vibroverb, Vibrolux) are designed so that signal is leaking between the two channels. The phase inverter is the last stage in the amp before the output tubes, and in all amps other than single-ended types with just one output tube (Fender Champ and Vox AC4, for example), this stage splits the signal into two reverse-phase strands to send on to those big bottles for final amplification. These premium tubes are manufactured in Russia. I own a SF Super Reverb and a SF Deluxe Reverb, both from 1970. « Reply #1 on: July 01, 2013, 01:10:06 pm ».
