Back Story of the F 159:
The author of the F159 is Jim Fosgate. Foz’s electronic design experience and excellence spans decades and coupled with Jolida’s decades of manufacturing experience, results in a unit which can provide our customers with a distinct improvement in turntable sound reproduction at an affordable price. In addition the phono pre-amplifier has a 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 who has built and tested 158 prototypes until finalizing his work in the 159th iteration. It is a classic Cascode circuit design and Jim has added a MOSFET to give the musical performance of tubes with the speed and detail of current solid state designs. Unlike most tube equipment it can product a perfect sine wave and uses zero negative feedback.
