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?

2SJ74 Datasheet PDF

December 21, Thanks that’s exactly what I meant: I’m not asking for you to share any precious circuit diagrams, just curious what other features you have added? 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?

I may be up for a few to make your order up Just a little bump up, with a question. I was thinking the would be better suited to coupling to a low impedance mic in a preamplifier design 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.

LIS is a U. I’m guessing its a lot. Toll Free Phone: Thats excellent – just what I was wondering – thank you muchly! February 25, I remember thinking something similar when reading the PDF. Thats great stuff Tamas – cheers! However, I still use the K in critical locations. Thanks a lot Fred! Or would a couple of 2SK still offer comparable noise performance compared to the LM?

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. I’ll check them out. So what else can be used when they are all gone?? The main amplifer in the buffer will be a Forssell I’m going to compare specs from the datasheets Microphone amplifiers, phono preamplifiers, audio amplifiers and preamps, discrete low-noise operational amplifiers, battery-operated audio preamps, audio mixer consoles, acoustic sensors, sonic imaging, and instrumentation amplifiers, wideband differential amplifiers, high speed comparators, impedance converters, voltage controlled resistors, sample and hold, source followers.

Engineers are invited to contact Linear Integrated Systems for assistance with application or special testing issues. 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 use a pair of the 2SK single in place of xatasheet K all the time, and yes, I do buy them in 10k quanities. Cascodes, current mirrors etc Cheers Tom. Tom, I am datashest at the November time frame to get one thousand. Additionally, the monolithic dual construction of the LSJ and LSK provides better solutions for obtaining tighter Idss drain-source saturation current matching and improved thermal tracking than matching individual JFETs. Common picks by professionals: Thanks for the tip Charlie!

I guess I might be able to swing a hundred Started by zebra50 The Lab. As a general rule how many JFets would one go through to get, say 20 pairs well matched?

Recommend JFETS for audio

But I will be using the devices in hopefully an instrumentation based amp for line level buffering. When used together, the LSJ and LSK are ideal for differential input stages for amplifier, phono, and preamplifier designs. Additional applications for the LSJ include voltage controlled resistors, thermal stable source followers, sample and hold, and current matched sources.

Not that the makes a poor line level device Thanks for the suggestions – when are you planning to buy some 2SKs? Recommended JFETs for audio and their application: I will try to get a load of s before there all gone I’m bummed that Toshiba has discontinued these and not offered a replacement.
