  Hi there,

  I have build several copies of this Pre. Ultimatly I found that using J-Fet (2SK147, selected for 10mA Idss) in cascode with the 417A resolves all noise problems without requiring selected, low noise WE417A's....

  The Linestage sounds best fully active and using the 5687. Implementation is also critical. Use Mills Wirewounds or similar as Anode Resistors and Rohpoint Precistion Wirewounds almost everywhere else. The Resistor for the First (75uS) EQ is best a Vishay with a non magnetic Silver Mica Cap preferred for the Capacitor. Foil & Film Polypropylen work well instead of ten Teflon Cap's.

  No Paper/Oil Cap's, Carbon Composite Resistors and the like pleas.

  Later Thorsten

  There is a site that has the info. I don't recall it will have to search for it, I have it written down. I meant to look it up and record it for my files. Hopefully, will get back to you or someone else is onto the case already. I do know that there is a site and a business on the web that is selling his gear. I'll check back...
