Fosgate designed Crosstalk Reduction Circuit (XT-R) which represents a distinctive electronic approach to solving crosstalk caused by a turntable’s cartridge and acoustic problems due to axial tilt. We have placed the name F159 to honor the designer which we will detail in the backstory on page 5.

Foz building and auditioning the circuits himself. Many people have asked us about the model number F159 which by most lights is rather like a fighter jet designation. The F in the model number represents an abbreviation of Foz, and the 159 identifies the circuit as the one hundred fifty-ninth iteration of the phono stage circuit that Foz has designed and built.
Right and Left Adjustment Knobs, Activation and Calibration Switches: Please note that the procedure to the XT-R circuit will be dealt with in the section “F159 XT-R Circuit Calibration Instructions”. The knobs and switches are utilized in calibrating for crosstalk reduction and axial tilt compensation.
For the built-in fuse, the value is 110/120 VAC 1 amp Fast Blow and for 220/240 VAC .50 amp Fast Blow. When replacing the fuse, make sure that your F159 is unplugged from the wall. The fuse is located in the upper part of the IEC receptacle in your preamplifier.
Getting Ready: In order to calibrate your Turntable, the F159 XT-R, it will require a Test LP. We use the Analogue Productions Ultimate Analogue Test LP, but there are others that can be used if they have separate left and right channel 1KHz test tone signals.
CAUTION: The F159 contains sufficient levels of voltage and current to be lethal. Do not tamper with a component or part inside the unit. Even with the power turned off, a charge remains in the energy storage capacitors for some time. Refer any needed service to your authorized Black Ice dealer or other qualified technician.
