He repeated the process for the PNP (B1560, replacing the B778). Two joints, four joints, six.
(NPN) are a widely used complementary pair of silicon power transistors primarily found in the output stages of high-fidelity audio amplifiers. Known for their high current handling and thermal stability, they are a staple for both professional repairs and DIY amplifier projects.

Ensure the circuit board is clean and that the mounting holes for the TO-3P package are aligned. He repeated the process for the PNP (B1560,
The are robust Darlington audio transistors. When they fail, the best persamaan (equivalents) are 2SD2155 / 2SB1429 or TIP142 / TIP147 . Always replace both channels (all output transistors in that channel) and ensure proper heatsink mounting with insulation. Known for their high current handling and thermal
Pilihan saya jatuh pada pasangan (NPN) dan 2SB778 (PNP). Kenapa? Karena pasangan komplementer ini terkenal kuat dan sering dipakai untuk menggantikan transistor final amplifier jadul yang voltage dan arusnya masih dalam batas aman.
