Thanks for the answer! There are no 4391s here, but one of the remaining 4-5 types of JFETs here is a switching JFET. This is the circuit diagram of the FM, AM/MW, and SW antenna amplifier circuit or we can likewise say it antenna preamplifier circuit which can be utilized to expand the faint signals of FM, AM/MW, and SW groups. It has a Drain-Source Voltage of 25 Vdc with a Drain-Gate voltage of 25 Vdc. It won't hurt anything to try other N-Channel JFETs. 2N3819 is an N- Channel - Depletion layer JFET that is widely used in RF-based audio equipment for amplification and other purposes. It will even solder easily enough to through-hole transistor pads (just make sure the pins are oriented correctly). The 4391 is the best that I've come across for this.

2N5485 Transistor Explained / Description: 2N5485 is an N channel JFET, in full form it is called junction field effect. 2N5654, 2N5949, BF244A, J105, J210, MPF102, PN4092. This post contains information about MPF102 pinout, equivalent, applications, explanation, specifications, features and many other useful information about this JFET. It just used to be readily available and worked ok. This post describes 2N5485 transistor pinout, equivalent, applications, features, explanation and other useful information about how and where to use this JFET. Even the MPF-102 isn't the best part for sync or integrator resetting.
Most JFETs will work, but the ideal part will be a "switching JFET". Can i drop in any n-channel JFET in there from the following: J201, 2N5457, BF245C? (i have these laying around from my diy guitar effect days, by the way these also disappeared from the shops i used to buy parts from) You'll wind up with a satisfying project that you'll appreciate for years. The collector dissipation is 500mW and maximum DC. 3 1 Publication Order Number: 2N4403/D 2N4403 Preferred Device General Purpose Transistors PNP. For using it as a switch to drive load it can handle 100mA of load with 30V. © Semiconductor Components Industries, LLC, 2007 March, 2007 Rev. It can be used as for any type of general amplification or switching. BC558 is a TO-92 packaged BJT transistor that can be used in many types of general purpose applications. Now you have the right design for an MPF102 JFET preamplifier. BC558 Transistor Explained / Description. Make the effort pay off My page offers a new preamp design, starting with the MPF102's specs.
MPF102-D27Z MPF102-D74Z MPF10206 MPF102G MPF1036 MPF1036. When you build a circuit, you go to a lot of work. I guess i need a FET there with high off resistance and low on resistance. MPF102 MPF102 Pinout Mpf102 N-channel Rf Amplifier MPF102 MPF102 Pinout Small Signal Jfet N-channel. TOPLEL wrote:The sync FET (that FET across the timing cap) in J3RK's PicoVCO is a MPF102.
