PCBA from $0（Free Setup, Free Stencil）: Hi friends, in this video I try to make a high power amplifier. This amplifier consists of 2 channels (stereo). Each channel uses 5 pairs of end transistors (2SC5200 & 2SA1943). In this assembly, I only used a 5A 47VAC transformer. But this amplifier can still be upgraded up to 10A 55VAC (if using the same box). The total budget for this amplifier is around $120.
