OK. What is far more likely is that the 48 Amp value is actually how much current is present when the power supply of the amp is shorted. Its available to the output section in the form of charged capacitance. This is used to help reduce IMD in the output section and is not something that the output section can pass to the loudspeaker (if you see what I did there 😁).
Yup, caught that. Shorted or driving Acoustats 😁 Talk about a vicious load for an amp. They were the reason for Ampzillas and Crown DC300 amps! The DC 300 would drive a cast iron pipe or a welder! 🤣
