Soft Start Circuits for Amplifiers
What are the pros and cons of soft start circuits for tube and solid state amplifiers? My VAC amplifiers do not have soft start circuits and are 200 WPC. I do notice my lights dimming due to voltage drop at power up and would imagine it's inrush current is hard on the KT 88s and other electronics? Your thoughts would be appreciated!
