I have an idea - you can just build it for me. Just make it light so shipping doesn't cost YOU too much.




edit: pacific riaa looks sort of familiar thanks

Thank you Vix.
Well, it is yet too early to compare...
My setup follows nelsons Schematic, only differing in the rail voltage which is 20V.
As far as I can judge right now the overall sound characteristic is a very detailed and very fine one. It has a somewhat "live" and a very transparent character.
So far.
But I think there is something wrong in my setup. I have to turn the input pots nearly all the way down, otherwise the sound is too much distorted. Unfortunately the bad pots I used don't give enough margin to realy find a good configuration. And of course I have to turn the volume at the output all the way up.
So there are some adjustment to do..

But from what I have heard till now I'am shure, it is very very promising
Manu

slightly increase source resistors
decrease PSU voltage

after some tweaking,you'll bang on topology limits ;
if you can find your source characteristics and output amp sensitivity in with topology layed boundaries .......fine ;
if not...... nice xperiment ,useful as stage somewhere.
