Audio power amplifier
From ivc wiki
This was a electronics course project, building an audio amplifier based around the LM1875 op-amp.
Circuit
The circuit was constructed after calculating the amplification, upper and lower frequency band, according to the specifications.
Final
This shows the final circuit, mounted to a flexi-glass plate to balance the enormous heatsink and protect the bottom traces.

Measurements
Measuring the input and output signal using a oscilloscope will verify if the circuit is designed correctly, which it turned out to be.
