Hey there.
This is a means to an end thread. =)
I want to explore a statement that Winston made in the trafoless mic pre section in regards to the Le Monstre Design. I'm not a fully qualified circuit bender yet, but I tend to learn best when I have specific application in mind.
Here's the quote:

Brad, have you played with Jean's 'Le Monstre' circuit at all? I have a couple of small-signal line amp circuits I built that were 'inspired' by this. One is single-ended but has the same elements as Monstre - BJT cascoding J-Fet's (// array in this case) that is fed into the so called 'Darlingnot' - and it is sonically the most tube-like squalid-state circuit I've cobbled together thus far. Harmonic Analysis is almost spot on that of a good triode valve.
.........
I have to say that I'm preferring the single-ended version that I built and this does not have the same issues with matching. Again, this amp consists of a parallel set of 2SK170BL's (4 in this case for 6dB theoretical noise improvement) with a single low-noise transistor as a cascode - a Fairchild KSC1845[/quote]
The link I found for The Monster design was at:
http://www.tcaas.btinternet.co.uk/hiraga.htm
My specific application is an 8X1 mixer. I've got an API 325 card that I plan to use for the combining network, which sets my power supply voltages at +/- 18V.
So the little static electricity discharge in my head says that the above could be a decent candidate for the 8 balanced mic inputs for this project. That is using the input stage, and cutting out the darlinnot stuff.
My main problem is that in electronics, I can't pass the blank piece of paper test yet ( this is an interview technique I use for software developers, which is simply hand someone a blank piece of paper and ask them to write a program =) ).
If I could get some help with a drawing of the above statement ( I get in big round concept what he's saying, but if I were to attempt a drawing of it, y'all would laugh your asses off), I'm more than happy to do a board layout for it so that the group can have another circuit to experiment with.
