HOOD-JLH2003 Gold-sealed Dual-channel Amplifier -PCB & DIY KIT & Finished Board Description:This is a finished board-one pair price, the set current of the finished board is 1A (per tube)This configuration of thermally conductive bridge angle aluminum (not a radiator), convenient for customers to connect to a large radiator;Do not leave the power on for more than 10 seconds, otherwise it may burn the power tubeHOOD JLH2003 is an upgraded work after JLH1969. It changes from JLH1969 single power supply to OCL dual power supply, and combines them. The maximum output power reaches 22W (at 8 ohm load). Compared with JLH1969 single power supply, JLH2003 outputs The frequency response curve is flatter (the frequency response curve is affected by no output coupling capacitor)The circuit magnification is 13 times, suitable for making power amplifiers and headphone amplifiers.This kit configuration:Taiwan-made metal film resistors, non-inductive power resistors, ELNA-C feedback capacitors, Panasonic blue robe decoupling capacitors, Siemens coupling capacitors, Toshiba small transistorsThe power tube is a second-hand folding machine tube 2N3055 gold-sealed tube to achieve the best sound quality. Each tube is set to have a static current of 1A, that is, the voltage difference between the two ends of the emitter cement resistance (0.1R) is 100MV. 22W pure class A power amplifier, heat is relatively large , Please pay attention to heat dissipationRecommended input voltage, plus or minus 18VDC (can be rectified by dual 15VAC-200W transformers)Single-sided PCB15.6*7.4*1.6MM, 1OZ copperShippment:1.Every parcel will be registered with tracking number. 2.International shipping requires complicated shipping procedures (such as both countries customs, transit stations etc.), also will be affected by many factors, such as holidays, weather conditions et.
