How have the auoformers changed over the years

Post by nashbap »

Hi Dave,

Been a very happy user of the original $200 autoformers since 2015.

I am planning on buying another pair and was wondering whether they have been changed in any way since 2015.

What inductance are they presently being set at?

Thanks. nash

no changes... Inductance is in the 200Hy range.

Is this figure frequency dependent especially at the low end? So 200H at 20Hz etc?

the 200Hy number is measured at 100Hz and will be the same at 20Hz.
