Default Re: Audiophoolery?

I'm afraid that in my experience Class A room heaters and other powerful amps too can blow quite big fuses at first switch-on, when the mains transformer energises itself and then starts charging all the power supply capacitors and warming up the near-short-circuit valve heaters. That was how I discovered the enormous range of blow characteristics which hide behind the letter T on a fuse.

Cheers,
