They are frequently sold as matched pairs, making them an affordable choice for replacing damaged components in vintage receivers or car stereos. Equivalent / Replacement Options
The and B778 (2SB778) are a popular pair of complementary silicon power transistors primarily used in the output stages of high-power audio amplifiers. They are designed to work together in a push-pull configuration, where the NPN-type D998 handles the positive half-cycle of the audio signal and the PNP-type B778 handles the negative half-cycle. This synergy allows them to deliver high-quality audio amplification with minimal distortion. Technical Specifications persamaan transistor d998 b778 install
A: Ini pertanda bias terlalu tinggi . Putar trimpot bias hingga tegangan di resistor emitor turun. Atau heatsink Anda terlalu kecil. Transistor 2SC5200 memiliki daya lebih besar, jika diset dengan bias sama, ia akan bekerja lebih dingin, bukan lebih panas. Jika panas, berarti bias melenceng.
