2n5457 Vs J201

The diagram I used called for a J201 FET but I couldn't find any around, so I sprang for this, as multiple sources claimed these 2N5457 JFETs would work. Happy to say that. 2n5457 i-12239 1個￥80 (税込) Nch J－FET 2SK2145－BL （2個入） 2sk2145-bl(te85 l f i-10724 1パック. The 2N5457 is perhaps the most commonly-used general purpose JFET for audio. It works great for buffers and clean boosts, yet its Vgs (off) value is low enough that it can also be overdriven easily, particularly in a mu-amp configuration such as Jack Orman’s Mini Booster. It’s a cross-reference for nearly everything.

The first high-frequency transistor was the surface-barrier germanium transistor developed by Philco in 1953, capable of operating up to 60 MHz. These were made by etching depressions into an N-type germanium base from both sides with jets of Indium(III) sulfate until it was a few ten-thousandths of an inch thick.

Designed by Don Tillman, this guitar pre-amp circuit design is dedicated for people who don”t like op-amps module. This circuit is a discrete JFET pre-amplifier design, use 2N5457 as the main component. It has low noise, low distortion, low feedback, overloads gracefully, is small, etc.

Overall gain is 3db (2X) or so. It uses about 1/2 ma, so a 9V battery will last a long time, you may also use simple regulated power supply with LM7809. It is possible to add a high boost switch in case you like by having it shunt the 2.2k ohm resistor with a 0.05uF cap (or other value; smaller cap = boosts only higher frequencies, as well as the reverse). You may simply placed in a 10uF capacitor across the 2.2k ohm resistor in order to up the gain.? You don”t like pre-amp circuit with op-amps..? then, just try to build this circuit. 🙂
