One of the most common questions we get asked is about ventilation of our class A amplifiers. We recommend an open stand so there is a free circulation of air available. Placing in a confined space or standing equipment directly on top of the amplifier is not recommended.
All #Sugden class A amplifiers have a circuit that regulates the standing current so this stops any possibility of overheating, even with the extreme temperatures many people are currently experiencing.
