Interesting ! What do you demonstrate with your "distortion box" at the ETF
How do you measure the distortion, with a soundcard or high tech FFT?

Why I ask these questions, I have two HP3581A Wave Analyzer and I will sell
one, if it works proper on the ETF. 
Also I like to learn more about distortion and distortion measurement and

Hi Peter

I'd suspect 230V, but I am not sure

If you like, I can bring a variac, so we can tune your distortion box to
whateer mains voltage required

Good to hear you'll be back this year

all the best
