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.

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. May 21, Started by zebra50 The Lab. Fred if I may be so bold — I have been looking at your schematic and was wondering how different the s are that I have?
Just a little bump up, with a question. But I will be using the devices in hopefully an instrumentation based amp for line level buffering. With the switch closed the total parallel capacitance is 0. Help FAQs Go to top. I remember thinking something similar when reading the PDF. Cascodes, current mirrors etc Cheers Tom.
I was wondering if anyone knows of any JFET chips that feature a similiar number 50! And J for switching?

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? I use a pair of the 2SK single in place of the K all the time, and yes, I do buy them in 10k quanities. Thanks for the suggestions — when are you planning to buy some 2SKs? Tom, I am looking at the November time frame to get one thousand.

The battery cable should be as short as possible and have a suitable cable diameter size to minimize loss, e. Product — Solar charge controller — LCD solar charge controller. A temperature compensated final charge voltage will extend the batteries lifetime and uses the optimum charge capacity. They have two different tripping mechanisms, the delayed thermal tripping mechanism for overload protection and the electromechanic tripping mechanism for short circuit protection.
