This is our ultimate Phono Preamp for your PAS upgrade. Sonically superior to all other Phono Preamp's we offer, this kit will frankly shame a lot of so-called high end Phono Preamp's currently on the market. It is a hybrid design using a JFET at the critical input stage to ensure super low noise operation and a MOSFET as an output buffer. It also has its very own onboard B+ regulator to ensure optimal performance. This Phono Preamp uses two 12AY7 Triode's. The PCB is manufactured to FR4-TG standards with ground planes on both sides to improve screening as well as component screen printing to make assembly easier.
IMPORTANT NOTE: We DO NOT RECOMMEND that the original PA211 power transformer be used for the Z Series PH20 due to the higher current demand of the Z-PH20 circuit. Instead, we recommend that you use one of our regulated power supply upgrades, click here.
NOTE: the tubes require a 24VDC supply for the filaments, not 6.3V or 12.6VDC!
A set of assembly instructions are also included, however, Tube's Are Not Included. Please note, that the photos are a general indication, and component colors and style can and will vary.
