A.C. RECEPTACLE:

The total power consumption for the RECT-O 50 is 2.5Amps @ 120 Volts. Thus, a 15 Amp circuit (which is what most house

circuitry is wired with) is adequate. Make sure the Euro style A.C. power cord is firmly seated in the power receptacle before powering

 

 

 

 

 

 

 

 

 

 

 

up the unit. Always connect the A.C. cord to a 3 terminal grounded socket. If none are available, connect

FUSE:

This is the A.C.’s (Alternating Current) main fuse and provides protection from outside A .C. fluctuations as well as power tube failure

damage. Should the FUSE blow, replace it with the same rating in a Slo-Blo type package. The domestic U.S. version requires a 2.5

SLAVE OUT :

This 1/4" jack provides a signal derived from the speaker jack. Perfect for using the RECT-O 50 as a master pre-amp, or additional power amps may be connected for more power when needed. Some players use this to derive an FX Send Signal and go to other

amps for their wet sound.

NOTE: Once a signal is taken from the SLAVE, it can not be inserted back into the FX Loop Return jack or a feedback loop will occur. Much like holding a microphone into the PA system’s cabinets...a loud high pitched squeal will occur.
