Finding the exact original part can be difficult, but you have many equivalent options. The key to a successful equivalent is to use a with equal or better specifications. If you upgrade the NPN, you must upgrade the PNP with a matching counterpart. persamaan transistor d998 b778 install
He typed the numbers into his distributor’s search bar. Discontinued. No stock. Obsolete.
), sehingga sangat aman digunakan, tetapi harganya lebih mahal dan sering dipalsukan.
Tighten the mounting screw firmly, but do not over-torque it. If the transistor is slightly tilted, it won't dissipate heat evenly, leading to "thermal runaway" and a quick "pop." Step 5: The First Power-On Never connect a speaker immediately after a repair. Power the amp on without a load. These match the original power and form factor specs closely
