Determining input power requirements of Audio Power Amplifiers
(OP)
Anyone have an answer on the AC input (VA)requirements for audio amps using a conventional linear PSU. For continuous RMS output normal input is 1.5 times o/p to account for transformer efficiency + heating losses etc. How much can you downrate the PSU for audio use (1000 Watts +). I've heard claims as low as a factor of 0.4

Normally for that power, you use to handle several parallel transistors, for not to drive more than 7 or 10 amps each, and from there, you may place a power output secondary voltage.
