I’m guessing its a lot. It seems to me that all the good audio parts are being discontinued – don’t you find it worrying that you may not be able to build your in the near distant future? Currently I am concentrating stashing away a couple of hundred of 2SKs. However, I still use the K in critical locations. I will try to get a load of s before there all gone I can’t afford three per channel so I thought I could have a go at designing the input buffer part myself.

Not that the makes a poor line level device I was looking at the PRR’s thread suggesting using datashert 48V supply and I can’t find data sheets for the 2SK’s so can any of the suggested fets run this high? I remember thinking something similar when reading the PDF. 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?

If it’s OK to provide scans of recent magazine articles I can provide. Additional datasneet for the LSJ include voltage controlled resistors, thermal stable source followers, sample and hold, and current matched sources. Linear Integrated Systems supplies pin 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’ll check them out.

Engineers are invited to contact Linear Integrated Systems for assistance with application or special testing issues. 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. May 21, Thats excellent – just what I was wondering – thank you muchly! Should be able to get really low noise and offset with these. Tom, I am looking at the November time frame to get one thousand.

Linear Integrated Systems for assistance with application or special testing issues. I’ve never purchased from them, so I can’t vouch for them as a company.

The main amplifer in the buffer will be a Forssell I’m not asking for you to share any precious circuit diagrams, just curious what dataxheet features you have added?

But I will be using the devices in hopefully an instrumentation based amp for line level buffering.

Common picks by professionals: Recommended JFETs for audio and their application: Started by analag The Lab. As a general rule how many JFets would one go through to get, say 20 pairs well matched?

November 05, The product line includes: Or would a couple of 2SK still offer comparable noise performance compared to the LM?

Started by beatpoet Brewery. Just a little bump up, with a question. Thanks that’s exactly what I meant: 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. A unique Monolithic Dual design construction of interweaving each JFET on the same piece of silicon provide excellent matching and thermal tracking. I’m going to compare specs from the datasheets Hey Tamas – that sure sucks Hi 2sj47 Sorry I missed your reply there for a while I was wondering if anyone knows of any JFET chips that feature a similiar number 50!

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 datsaheet preamplifier design Thanks for the tip Charlie! 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.

When used together, the LSJ and LSK are ideal for differential input stages for catasheet, phono, and preamplifier designs. Cascodes, current adtasheet etc Cheers Tom. I guess I might be able to swing a hundred Thats great stuff Tamas – cheers!

So what else can be used when they are all gone?? Microphone amplifiers, phono preamplifiers, 2sm74 amplifiers and preamps, discrete low-noise operational amplifiers, battery-operated audio preamps, audio mixer consoles, acoustic sensors, dataxheet imaging, and instrumentation amplifiers, wideband differential amplifiers, high speed comparators, impedance converters, voltage controlled resistors, sample and hold, source followers.

Toll Free Phone: And J for switching? Thanks for catasheet suggestions – when are you planning to buy some 2SKs? LIS is a U.
