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
A bit more "headroom" than the D998/B778 without requiring major circuit adjustments. 3. The TIP Series: TIP35C / TIP36C persamaan transistor d998 b778 install
Installing power transistors requires more than just soldering; heat management is the most important factor. Step 1: Surface Preparation Test: Use a multimeter on the "Continuity" setting
Most D998/B778 setups use the heatsink as a common ground or a different voltage rail. You use a Mica insulator or a Silicone pad between the transistor and the heatsink. The TIP Series: TIP35C / TIP36C Installing power
Very common, higher power handling, excellent for heavy bass.
By choosing a high-quality equivalent like the and focusing on clean insulation during install , your amplifier will likely perform better and cooler than it did with the original factory parts.
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)
