About EB Sources — e-gun manufacturer and repair shop in Concord, California

EB Sources was founded in 2001 by Larry Willitzer, after years spent rebuilding vacuum e-gun systems at Semicore in Livermore. He started the company to build a better e-gun — one you could clean without pulling the magnet, and keep in production instead of waiting on a regauss. That's still the whole point.

Founded in 2001 on four decades of hands-on e-gun experience. Made in the USA, in Concord, California — and shipped and serviced worldwide.
