WZ-86 Conrad-Johnson PV-12PH Poem Wire Gain 18dB Bile Pre-Amplifier

Description: Title： WZ-86 Conrad-Johnson PV-12PH Poem Wire Gain 18dB Bile Pre-Amplifier Specification: 1. The blank board is a 2mm thick double-sided gold-plated PCB.2. Spare parts (need to be welded by yourself, excluding potentiometer and bile duct, need to be purchased separately).3. The finished board is a semi-finished product that has been installed and debugged (excluding bile ducts, which need to be purchased separately).4. Approximate size of the finished product: length 173mm, width 110mm, height 65mm.5. The installation hole distance is 161.036mm*97.536mm, and the distance between the two bile duct holes is 100mm.In order to facilitate your installation and debugging, the circuit diagram and component table are provided with the board.6. The panel is powered by the extremely high voltage +325V, and the filament low voltage is 12.6V. It is recommended to use our WZ-35 power supply board.The circuit of Conrad-Johnson PV-12 and Audio Note M7's preamp is basically the same, we default the value of PV-12. PV-12: The gain is about 18dB, the maximum output is about 20V, the distortion is about 0.25%, and the output impedance is less than 500Ω. Purchase board need to know: ①In order to use the bile duct you already have on hand, the finished product does not have two tubes. You can choose 12AU7 or ECC82 or 6189. The tubes of the AU7 family can be used. Just pay attention to the filament voltage.②Coupling capacitors do not have strict requirements on capacity, you can also try to tune with some substitutes on your hands, 1-5uF is available.③We use genuine ALPS27 potentiometer for the finished board. Packing: 1*Empty Board or Spare Parts or Finished Board of Pre-Amplifier
