Persamaan Transistor: D998 B778 Install [upd]

Monitor the temperature. If the transistors get hot within seconds while idling, turn it off—there is a bias issue or a short. Summary Table Equivalent (Best) Equivalent (Alternative) B778 (PNP)

Test: Use a multimeter on the "Continuity" setting to ensure the back of the transistor is NOT touching the metal heatsink directly. Step 3: Thermal Paste Application persamaan transistor d998 b778 install

If you cannot find the exact part numbers, you need a pair that meets or exceeds the voltage and current ratings while maintaining a similar frequency response. 1. The Upgrade Choice: 2SC5200 / 2SA1943 Monitor the temperature

Are you repairing a or a home stereo system ? Knowing the device can help me give you more specific advice on setting the bias current! Step 3: Thermal Paste Application If you cannot

Because they are popular, watch out for "fake" or low-quality clones. 2. The Direct Match: 2SD1047 / 2SB817 These are very close in characteristics to the originals. Specs: 140V, 12A, 100W.
