Active, serial FX-Loop for a subsequent installation in an existing tube amplifier
The FX-Loop works with two LND150 in the send and in the return stage. The send and return level can be adjusted to their optimal value with two potentiometers. The Loop works with the present high voltage of the amplifier.
It has two inputs for low and high signal levels.
Input Levels:
InA: 30 - 60 Vpp, max. 65 Vpp
InB: 10 - 15 Vpp, max. 18 Vpp
The FX-Loop utilize POTENTIALLY FATAL HIGH VOLTAGES.
Seek help from a competent technician if you are in any way unfamiliar with high voltage circuits.
Use at your own risk.
