Sebelum memilih komponen pengganti, Anda harus memahami karakteristik asli dari pasangan komplementer ini. Transistor D998 (2SD998) bertindak sebagai kanal positif (NPN), sementara B778 (2SB778) bertindak sebagai kanal negatif (PNP). Keduanya umumnya dikemas dalam bodi atau TO-3PF .

Clean the heatsink thoroughly. Remove all old, crusty thermal paste using isopropyl alcohol. Any debris or "burrs" on the metal can puncture the insulation and cause a short circuit. Step 2: Insulation (The Mica Sheet)
The and B778 (2SB778) are high-power silicon transistors typically used as a complementary pair in audio amplifier output stages. In this setup, the NPN-type D998 handles the positive half-cycle of the audio signal, while the PNP-type B778 handles the negative half-cycle, a configuration commonly known as a push-pull or Class AB amplifier.

Apply a thin, even layer of (heatsink compound) on both sides of the insulator. Do not use too much; a "pea-sized" amount spread thin is enough. The goal is to fill microscopic air gaps, not to create a thick barrier. Step 4: Secure Mounting
