[QUOTE="charles, post: 1042943, member: 2759"] Many years ago I did some extensive distortion measurements and spectral analysis on a Radford STA 15 series III at rated output. I was then very surprise at the low distortion figures. I used a digital audio analyser and a FFT spectrum analyser (instruments) to conduct the said measurements. Maybe it is time to do it again. The Radford STA 15 is my all time favourite valve amplifier. [/QUOTE]
