Copy NHB-108 150W Power Amplifier DIY Board / Kit Amplifier Circuit Without Negative Feedback
All Original Components
1. Two pieces of PCBs for amplifying circuit (PCB size 90*135mm, 2.0mm FR4 sheet, copper thickness 2OZ, Immersion gold 4um, full flying probe factory inspection)
2. Panasonic M Series Electrolytic Capacitors (RS, Element1, Manual Matching 1%)
3. Vishay PR02, AC03 High Power Resistor (Manual Match to 1%)
4. Philips MRS25 1% 0.5w resistance (Manual Match to 0.5%)
5. Philips Precision Silver Film Capacitor (Manual Match to 0.5%)
6. WIMA MKS-4 Capacitor (Manual Match to 1%)
7. Imported 1W Zener diode (Manual Match to 1%)
8. Original Transistor (graphical instrument 3~5% pairing)
9. Insulation pieces, insulation particles, screws and other spare parts
10. SCNP midpoint stabilization module
11.There are two options for the product. DIY KITS needs to be welded by yourself. If you are not familiar with welding, please buy finished boards
12.The product does not have SCNP in the picture. Buyers need to pay $ 20 if needed! (SCNP module, adding this module can reduce the mid-point voltage drift amplitude)
13.The transformer uses dual 35VAC ~ 40VAC, the recommended power is 300W ~ 500W, one transformer per channel.
The original electrolysis uses Philips BC101 series 63v 22000uF electrolysis
