Electronic Works Mosfet Audio Amplifier Driver Board 500 to 2000 watt kit (it is not Amplifier its only Driver Board kit)

Powerful sound

इस ड्राइव के साथ बास ट्रेबल कीट अलग से मिल जाता तो अच्छा होता ...क्युकि साउंड कि क्वालटि बास ट्रेबल कीट से ही होता है... अच्छा से अच्छा bass trebal कीट यूज किया ,लेकिन अफसोस हमे अच्छी क्बालटि बाले कीट नही मिला 🌿

Like 100% best performance but price 100% extra in tamil nadu only 600 rupes but performance low same material same cirqute but your rate is too high

Came with a shorted 2N5401 transistor in the differential stage and a DC offset of 1 volt across the speaker. DC offset came down to 20mv after the 2N5401 was replaced. And VR1 is for adjusting the quiescent current. Seller should not mislead buyers by giving wrong information. Most buyers will not even understand what quiescent current adjustment is. Some basic documentation should be given along with pcb for guiding inexperienced buyers. Make in India will succeed only if we take pride in what we manufacture. Low price generally translates to low quality. Just assembling a pcb and selling it without running basic tests will In the long term ruin your business. The MJE340 bias transistor should be on the heat sink along with the output transistors. Otherwise when the bias is set there will be thermal runaway and the output transistors will be destroyed. Bias has to be adjusted to correct crossover distortion. Nobody today uses the poor quality 2k preset you have put on the board. It is the worst component on the driver board.

Sound amazing

Super

Super quality easy to Amplifier repair
