Persamaan Transistor D998 B778 Install Repack Access

Sebelum mencari persamaan, penting untuk mengetahui spesifikasi dasar kedua transistor ini agar penggantian tidak menyebabkan amplifier overheat atau rusak. 2SD998 (NPN), 2SB778 (PNP) Tegangan Kolektor-Emitter (VCEO): -120Vnegative 120 cap V Arus Kolektor (IC): 10A10 cap A Disipasi Daya (PC): Package: TO-3PML (Paket daya tinggi) 2. Persamaan Transistor D998 B778

This is the most common "upgrade." They are rated for and 150W (230V), making them much more robust than the original D998/B778.

The installation wasn't going to be a simple drop-in. The original D998 and B778 had a specific lead spacing. Elias grabbed his insulated pliers and carefully bent the leads of the new transistors to match the old PCB footprint. He applied a thin, even layer of thermal paste to the back of the new casings—white grease that looked like face cream—and slid the orange mica insulators underneath. persamaan transistor d998 b778 install

: Jangan pernah mencampur tipe berbeda. Jika Anda mengganti D998 dengan 2SC5200, maka pasangannya (B778) wajib diganti dengan 2SA1943.

Finally, it was time for music.

Might slightly change the "brightness" or clarity of the high-frequency audio. Step-by-Step Installation Guide
