Hai all,
I'm drawing and simulating a PP amp; it started as a Nelson Pass's Aleph Mini Clone, then evolved into an Hybrid (tube/mosfet) and now it is a full SS PP amp.
I intend to use a pair of N jfet at the input (as per Aleph Mini J), as a differential pair (or LTP).
I've seen Nelson Pass suggest 2SJ109 device, which is unfortunately not available anymore.
I'm simulating the amplifier using two BF862 device, which looks promising.
They are unfortunately available in the SOT23 package, which is not really a DIY-friendly package.
So, my question is: can you suggest me a N Jfet model, maybe in TO92 package, which can be used here, and which you like?
Of course a dual Jfet would be perfect.
Here is the schematic and LTSpice simulation (rename the txt file into a asc file).
Please check also the schematic, if you can it can be improved let me know.
Ciao,
Giovanni

I am confused.
You like Mosfets.
Do you know how and why they operate?
I know mosfets, yes.
Your statement means I forgot something important in my schematic?
I cannot understand what do you mean.
Please explain.
