About the amp

For the tube (valve) complement in a stock blackface Tremolux (AA763 circuit), it typically includes the following, based on Fender’s schematics.

• Power tubes: 2 x 6L6GC (providing around 35 watts of output power; these deliver the characteristic clean headroom and smooth breakup of mid-1960s Fender amps).
• Rectifier tube: 1 x GZ34 (5AR4) this is a tube rectifier, contributing to the amp’s sag and compression under load.
• Preamp tubes: 3 x 12AX7 – also known as EC83 (one for the normal channel preamp, one for the vibrato channel preamp, and one dedicated to the tremolo/vibrato circuit).
• Phase inverter tube: 1 x 12AT7 – also known as ECC81 (drives the power section for balanced signal splitting).

Tube positions (viewed from the rear of the chassis, with V1 on the right):

• V1: 12AX7 (normal channel preamp)
• V2: 12AX7 (vibrato channel preamp)
• V3: 12AX7 (tremolo oscillator)
• V4: 12AT7 (phase inverter)
• V5: GZ34 (rectifier)
• V6 & V7: 6L6GC (power tubes)
