Here's a link on the subject of <a href="http://www.otlamp.com/articles/tomcik/index.html">DF</a> you might find interesting.

Thorsten,

Interesting idea, but one I'll have to pass on trying at the moment, though I look forward to other people's versions. My living room/workshop is already too cluttered with bits for the amps I'm currently building.

Cheers

Who said I use my speaker drivers close to the resonance?

It was posted as an FYI, but make of it whatever you like, IDGAFF.

The notion that a particular type of distortion is the
essence of a simple and/or single-ended Class A
design leads lots of people to hope that they can
simulate this sound by introducing those distortions
into a different and/or more complex circuit. It has yet
to work as far as I can tell.

I always say that if you want tube sound, you use tubes.

It's not just the distortions, it's the frequency response contouring, which varies with signal level.


More coffins, Warden?
No, thanks, I've had enough

Now listen Nelson, first, do not steal my lines and secondly, please give me a LITTLE more credit for my research. Hell, how about YOU take the time knocking up my suggested circuit and tell us how you like it, honestly speaking.

There is a first time for everything. I could give one of my main secret's here by suggesting to replace in the discussed circuit one specific resistive component with a reactive one, but I said "sound alike" not "sound the same" amplifier....

So do I mate, so do I. But some people want "most of tube sound" with as few tubes as possible.

Me, I want that too of course, but I manage mostly without solid state (I do use it to rectify heater voltage though, shame on me), but I still like as few Valves as possible (at the moment 4 Valve stages from MC Pickup to Speaker, plus three transformers inclusive volume control and quite a few inductors as Anode Loads, Equalisers and grid leak path).

Was it Picasso or Steve Jobs that said

"Good artists copy. Great artists steal."

BTW, you have to publish your ideas before we
can appreciate (steal) them....

MuuuHahahahahah

More likely Mr. Microsoft.

Hi Kuei,

I too came about the idea of using a tubed pre-amp with my "inverted gainclone".
A friend of mine built this pre-amp:

Do you think I can expect any good results with using that one?
