FET Preamplifier, Part 1 |
Now, with Easy to Find Parts! Some time ago, J. Donald Tillman designed an elegant JFET guitar preamplifier. He posted the circuit on the Web. Overnight, this circuit became very popular. And it's still a winner today. The reasons why are easy to see. This amp is easy to build. The circuit works like a champ. And the JFET's tube-like warmth sounds great. Plus, the high-impedance input won't load your guitar. At the other end, the medium output impedance combats high-frequency losses due to loading and long cables. And by the way, this FET preamp is great for microphones, too! Bad News...and Good. Unfortunately, Tillman's amplifier requires a J201 FET. The J201 is a very special device and an excellent choice. Yet it's uncommon to hobbyists. But my site solves the mystery. I've designed a similar preamplifier with an everyday Radio Shack JFET.
Achieve results that you can be proud of! When you build a circuit, you go to a lot of work. Make the effort pay off! My page offers a new preamp design, starting with the MPF102's specs. Now you have the right design for an MPF102 JFET preamplifier. Build carefully. You'll wind up with a satisfying project that you'll appreciate for years. Go to Page: 1 2 3 4 5 6 7 8 FAQ Next
