Capable of drawing over 45A from a 120V AC line at full capacity when driving a 2 ohm load

 

Is this a 220/240V unit?

I was going to ask the same thing. The AC plus looks like an Australian from the partial photo visible on my iPhone but worth confirming that too.

Apologies all, this is my bad (Jason) - in the original specs posted online (which i used) the amp was configured to draw over 45A from a 120V AC line in North America BUT when using it with an Australian power supply (typically 220V to 240V), which it has, the current draw would be different due to the increased voltage.

So, using a bit of high school physics, if the voltage is increased from 120V to 220-240V, and if the power requirement remains the same, the current draw would theoretically halve. Therefore, if the No.333 draws 45A at 120V to achieve a certain power output, at 240V under the same conditions, it would draw approximately 22.5A.

Thanks Len - out of interest and from a self confessed technical Luddite does that affect output power figures as well - ie do we halve the quoted figures above? Gorgeous looking beast 👍❤️

No - the specified output remains as quoted. Yes - this is an imposing looking piece.

Hi Andythiing - great question! Broadly speaking amplifiers can achieve the same power output specifications regardless of whether operating on a 120V or a 220V-240V power supply, provided they are designed to accommodate both voltages. High-quality audio amplifiers are often built to work internationally, able to handle different mains voltage levels while maintaining consistent performance. This adaptability is crucial for maintaining their sound quality and power output across various global power standards.
