    TUBE EFFECTS LOOP This is a 6N17B sub-miniature dual-triode vacuum tube-based series FX loop. It employs high voltage, has zero- loss, is built on a PCB and includes an optional true-bypass switch. This all tube FX loop add-on module can be fitted to virtually any guitar tube amplifier.

    FX LOOP INSTALLATION Installing this module will require you to work with high voltage. Previous experience with tubes and/or tube amplifiers is mandatory. It’s recommended to have the module installed by an amp technician. COMPLETE THE Fx BOARD The Fx board has an option to determine the spacing of the SEND and RETURN jacks. They can be spaced 1 inch or 1-1/2 inch apart.

    Ensure that that the proximity of the Vacuum tube to components is no less than 1/4” . At that distance, the temperature of the component will reach a safe 40 degrees C which is less than half the typical temperature allowed.

    6. INSTALL THE FX BOARD With all the wires connected, remove the nuts from the SEND and RETURN jacks. Fit them through the previously drilled holes in the chassis. Use the fibre washers to set the depth of thread in the hole.

    USING THE Fx LOOP In stock configuration, installing the Fx Loop in active mode will reduce your SEND signal after the buffer (cathode follower) stage of the circuit. On RETURN, the signal is input into a basic triode gain stage that adds gain.
