220V Separated HiFi Power Amplifier Pure Rear Stage 70Wx2 Reference for Goldmund JOB4 Amplifier Circuit

220V Separated HiFi Power Amplifier Pure Rear Stage 70Wx2 Reference for Goldmund JOB4 Amplifier Circuit

Audio Performance:
- Each channel has a power of 8ohms/70W, with a clean and smooth bottom that is free of impurities, hydrated and glossy, without any burrs. With a noble cultural atmosphere typical for Goldmund, it has high analytical power, high frequency and delicacy, accurate sound structure and position sense, moderate thickness in the middle and low frequencies, and sufficient low-frequency sense. It can handle the vast majority of speakers on the market.

Features:
- The entire machine adopts the famous JOB4 circuit, which is used by many reference for Goldmund. The circuit architecture and parameters are completely consistent with Goldmund, and the internal circuit board are structured with the upper and lower layers.
- The terminal adopts 807 24K gold-plated RCA input, with a golden light, oxidation resistance, and reliable contact; Large pure copper terminal blocks, used year-round without blackening, with high output current.
- The output protection circuit uses an Omron relay to prevent instantaneous impact on the speaker during startup and remove the popping sound generated during startup.
- The material used in this machine is solid, and the PCB uses double-sided board technology. A pair of K170 field-effect transistors are used for input, and one pair of SK1057/J162 is used for output per channel. The main filter capacitor adopts for Nikon capacitor. Two customized pure copper wire 260W power transformers are used for the left and right channels, with dual AC40V main voltage used to ensure good dynamic power output.
