Component placement drawing for the Apex AX 20 amplifier board, a 61 KB PDF. It shows where each resistor, capacitor, transistor and connector sits on the PCB, which makes it the main reference when populating a new board or checking an existing one for wrong or missing parts. Use it with the matching copper-side artwork to relate component positions to the tracks. Verify the orientation of transistors, diodes and electrolytic capacitors before power-up.
