the signal path between preamp and power section as it occurs in the Dual and Triple Rectifier Heads. To achieve this duplication, a driver tube responsible for the effects return stage and all related circuitry in the 2:100 must be removed and this includes the LEVEL Conbtrols as they are part of this circuitry. As a result, when using the RECTO INPUTS, you will use the Recto Pre LIVE OUTPUT Control as your overall final master level control.
TUBE BIAS: Your 2:100 was designed with versatility in mind. The BIAS SWITCH allows you to adapt the power output section of the 2:100 in order to use the other classic pentode power tubes, the British style EL 34. These tubes are largely responsible for the

RECTO INPUT MUST MATCH TUBES
This characteristic is sometimes preferred for sounds that range from a soft clip that would be used for chording or soloing, to an all out high gain crunch or lead sound. Players that use mostly these types of sounds may prefer the EL34 clip to the 6L6’s that come standard in the 2:100. If you need a variety of sounds and rely on a clean chording sound much of the time, you will likely prefer the stock compliment of 6L6’s that the 2:100 comes fitted with. We feel the 6L6 is a more balanced sounding tube that produces plenty of harmonic lushness, while at the same time delivering the rich lows that are crucial to both a warm clean sound and huge, tight high gain crunch sound.
