Output Stage parts diagram: 1 output transistors, 2 bias network, 3 output heatsink, 4 output resistor, 5 SMD passive (R/C/L). 10 parts in 5 top-level items. — Output Stage parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.

#	Part	Qty	What it does
1	Output Transistors	4×	Complementary pairs
2	Bias Network	1×	Quiescent current setting
3	Output Heatsink	2×	Per-channel heat dissipation
4	Output Resistor	2×	Build-out resistors
5	SMD Passive (R/C/L)	1×	Surface-mount resistors, capacitors, and inductors, typically in 0402 to 1206 packages, that set voltages, filter noise, and time signals on a circuit board.
