Default SE ultralinear amplifier generate a lot of Odd harmonics ?

Hi,

Does anyone know if an SE ultralinear amplifier generate a lot of Odd harmonics compare to a triodes SE?

Does anyone know the Mr willis's amplifier ( SE 813) sound very well?

Thank.

Probably less (assuming you use a little global NFB to reduce Zo, as I recall Zo tends to be a bit high in UL). It might be higher in relation to the 2nd harmonic, but both will be much lower (perhaps 2% total compared to 5%).

Just guessing, I haven't built an UL amp yet.

Have a look at the various UL curves here and do a bit of loadline analysis and you should have a fairly good idea.

I haven't built an UL amp either, but I think that distortion would likely be higher - the curves are less evenly spaced in UL when comparing with triode mode.

In my experience, yes, more odd harmonics and the spectrum extends further. But it depends on the application.

I don't like UL's and wouldn't waste a good 813 on one.
