McGillwell FET Booster
Based on the McGillwell FET Booster
From the post
Since we're posting tiny circuits today, i thought i'd post a recently traced booster. No input cap, no power filtering or any other modern day trinkets. Tiny booster with outside the box thinking in design. Thanks for trace to Bernardduur at FSB.
