Home Amp/Preamp Asylum

Looking for a new Amp or Preamp? If you're after tubes, post over here.

RE: I've never heard one, do they sound that good?

It's losely based on a Hitachi application note from '77, and then I believe the Maplin 150 shared elements of it. I believe Erno Borbely used elements of this when at Hafler.

An article appeared in Electronics World in August, 2001 that has a modified and updated schematic. I have substituted some parts and use heavily biased vertical MOSFETs.

I am wanting to try lateral MOSFETs as these are supposed to sound even better and would allow me to get rid of the bias circuit and replace it with one fixed resistor.

I'll see if I can dig it up.









Never attribute to malice that which can be adequately explained by stupidity.
