Started by zebra50 The Lab. Please state the specific application in which you desire to use them. Common picks by professionals: Thanks 2su74 exactly what I meant: Recommended JFETs for audio and their application: And J for switching?

If it’s OK to provide scans of recent magazine articles I can provide. Thats great stuff Tamas – cheers!

Just a little bump up, with a question. 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 was wondering if anyone knows of any JFET chips that feature a similiar number 50!

Or would a couple of 2SK still offer comparable noise performance compared to the LM? I’m going to compare specs from the datasheets Thats excellent – just what I was wondering – thank you muchly!

I remember thinking something similar when reading the PDF. I was thinking the would be better suited to coupling to a low impedance mic in a preamplifier design 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.

The main amplifer in the buffer will be a Forssell I can’t afford three per channel so I thought I could have a go at designing the input buffer part myself. Hey Tamas – that sure sucks I will try to get a load of s before there all gone Should be able to get really low noise and offset with these.

I’ve never purchased dataseet them, so I can’t vouch for them as a company. 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.

However, I still use the K in critical locations. I’m bummed that Toshiba has discontinued these and not offered a replacement.

Thanks a lot Fred! 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? 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? I’m not asking for dxtasheet to share any precious circuit diagrams, just curious what other features you have added?

Cascodes, current mirrors etc Cheers Tom. So what else can be used when datashset are all gone??

Hi Tamas Sorry I missed your reply there for a while Thanks for the suggestions – when are you planning to buy some 2SKs? I may be up for a few to make your order up I guess I might be able to swing a hundred Tom, I am looking at the November time frame to get one thousand. Currently I am 2sn74 stashing away a couple of hundred of 2SKs.

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?

Thanks for the tip Charlie! I’ll check them out. 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. As a 2sn74 rule how many JFets would one go through to get, say 20 pairs well matched? 2ej74 guessing its a lot. February 25, December 21, May 21, November 05, ,
