All components can be purchased from Digi-Key but the chokes and the Op-Amps. For those of you in the U.S. who are interested in constructing this superb pre-amp, I have two of the 10 H/30 Ohm/10mA chokes from SteinMusic (located in Germany for sale). Brand new, never used. Will ship anywhere in the U.S. for actual shipping cost by U.S. Mail from Los Angeles, CA. Price is $70/pair. Contact me at markjohnson@cox.net if you're interested.
