#103: Some changes to my OPA541-based power amplifier for function generators

This short video documents some changes I did to make the amplifier more stable and less prone to overheating. Its basically changing the heat sink on the OPA-541 module to a larger one, cutting a slot into the PCB to improve airflow and reducing the rectifier heat sink to make space for the OPA-541's larger heat sink.
