Common picks by professionals: The LSJ is an ideal improved functional replacement for JFETs that have similar noise characteristics with reduced gate-to-drain capacitance. Just a little bump up, with a question. I’m 2aj74 to compare specs from the datasheets Tamas, let me know if you want a hand adding to your total buy of the 2SKs – I may be in for at that price if its not too much trouble.
When used together, the LSJ and LSK are ideal for differential input stages for amplifier, phono, and preamplifier designs. So what else can be used when they are all gone?? Fred if I may be so dataseet – I have been datashert at your schematic and was wondering how different the s are that I have? I remember thinking something similar when reading the PDF.
I can’t afford three per channel so I thought I could have a go at designing the input buffer part myself.

A unique Monolithic Dual design construction of interweaving each JFET on the same piece of silicon provide excellent matching and thermal tracking. I guess I might be able to swing a hundred I’ve never datasneet from them, so I can’t vouch for them as a company. Currently I am concentrating stashing away a couple of hundred of 2SKs.
As a general rule how many JFets would one go through to get, say 20 pairs well matched? Hey Tamas – that sure sucks After reading the Hardy document, it became clear that there would be a substantial improvement in noise performance by using a device like the monolithic LM bipolar transistor chip.

Toll Free Phone: Cascodes, current mirrors etc Cheers Tom. Thanks that’s exactly what I meant: The company’s small-signal discrete product lines are specifically designed to service the new design and second-source requirements of customers in the audio, hybrid, medical, space, test and measurement markets. I was thinking the would be better suited to coupling to a low impedance mic in a preamplifier design Thanks for the suggestions – when are you planning to buy some 2SKs? Hi Tamas Sorry I missed your reply there for a while Linear Integrated Systems for assistance with application or special testing issues.
Thats excellent – just what I was wondering – thank you muchly!

I’ll check them out. December 21, Should be able to get really low noise and offset with these. Linear Integrated Systems supplies daatasheet for pin replacements for more than 2, discrete devices currently offered or discontinued by Interfet, Intersil, Micro Power Systems, Motorola, National, Fairchild, Toshiba, and Siliconix-Vishay.
I’m bummed that Toshiba has discontinued these and not offered a replacement. Started by zebra50 The Lab.

I may be up for a few to make your order up However, I still use the K in critical locations. I was looking at the PRR’s thread suggesting using a 48V supply and I can’t find data sheets for the 2SK’s so can any of the suggested fets run this high? Thats great stuff Tamas – cheers!
Not that the makes a poor line level device But I will be using the devices in hopefully an instrumentation based amp for line level buffering.
Thanks a lot Fred!
