Goltilkis The 2N has the gate on right pin when viewing the flat side of the package. View the Media Kit. The tone stack forms a sort of RC notch filter. And J for switching?

No, create an account now. Does anybody here have experience with this circuit? If customers intend to use NEC devices for applications other than those specified for Standard quality grade. The recommended applications of. Your email is included with the abuse report. While NEC Corporation has been making continuous effort to enhance the reliability of its semiconductor devices. On Tue, Nov 17, at 2: I read about the design, dont remember where, of the input amplifier to the Tek scope.

The look of panic on my face was replaced by the look of deep confusion. Some people may remember my HV multiplier problem with my from a little over a year ago.

Whereas I will be soldering at the board anyway, guess I mount tiny small transistor sockets and experiment a bit using several fets to get myself comfortable working with these. Are datashet FETs deteriorated? Newer designs use a low input bias current operational amplifier in place of the bottom JFET however while this allows for better offset drift with temperature, they will usually have worse overload recovery.

Arajin The main amplifer in the buffer will be a Forssell But I will be using the devices datashest hopefully an instrumentation based amp for line level buffering. Or would a couple of 2SK still offer comparable noise performance compared to the LM? Thats excellent — just what I was wondering — thank you muchly! I remember thinking something similar when reading the PDF. With the switch closed the total parallel capacitance is 0. December 21, However, I still use the K in critical locations. Common picks by professionals: Recommended JFETs for audio and their application: We can get a rough idea of the operating range for a given gate voltage by looking at the channel current vs.

Nagis Please state the specific application in which you desire to use them. This may not be a problem in your application, since the FET stage is immedately followed by a level pot, so you can compensate for the additional gain. Not much of a notch there. I may be up for a few to make your order up I was thinking the would be better suited to coupling to a low impedance mic in a preamplifier design I guess I might be able to swing a hundred The main amplifer in the buffer will be a Forssell The most important characteristic now is how much affect the gate voltage has on the current flow through the channel.
