Started by zebra50 The Lab. The low side cutoff is now about 60 Hz. And J for switching? Please state the specific application in which you desire to use them.

The main amplifer in the buffer will be a Forssell The cutoff frequency for the low side is Hz, and the cutoff frequency for the high side is Hz. I guess I might be able to swing a hundred However, I still use the K in critical locations. I’m not asking for you to share any precious circuit diagrams, just curious what other features you have added?

The tone stack forms a sort of RC notch filter. You should be able to get a reasonably decent tone control by replacing the 22K resistor with a combination 3. The maximum gate voltage relative to source or drain on the 2N is only half that of the 2SK30A; 25V compared to 50V. But I will be using the devices in hopefully an instrumentation based amp for line level buffering.


I was thinking the would be better suited to coupling to a low impedance mic in a preamplifier design Now, when you flip the switch the two capacitors in parallel add, forming an effective capacitance of 0.

N-Channel JFET Transistor, Audio Amp 50V 10mA – NTE

I was wondering if anyone knows of any JFET chips that feature a similiar number 50! The mid scoop dayasheet pretty extreme. Should be able to get really low noise and offset with these. Recommended JFETs for audio and their application: Currently I am concentrating stashing away a couple of hundred of 2SKs.

Cascodes, current mirrors etc Cheers Tom. Or would a couple of 2SK still offer comparable noise performance compared to the LM? Thanks a lot Fred! Ratasheet if I may be so bold – I have been looking at your schematic and was wondering how different the s are that I have? The values in the tone stack are then pretty close to the tone stack used in the “Tone 2” position on the FY Hey Tamas – that sure sucks Join the HC Newsletter.

I’m bummed that Toshiba has discontinued these and not offered a replacement. 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.


I’m going to compare specs from the datasheets Thanks for the tip Charlie! If I were building this circuit, and I had the 2N available, I’d give it a shot. Just a little bump up, with a question.

The 2N has the gate on right pin when viewing the flat side of the package. Started by beatpoet Brewery.

Previous 1 2 3 Next. Hi Tamas Sorry I missed your reply there for a while It seems to me that all the good audio parts are being fte – don’t you find it worrying that you may not be able to build your in the near distant future?

So what else can be used when they are all gone?? February 25, That’s a pretty big chunk of the mids. Thats excellent – just what I was wondering – thank you muchly! I remember thinking datashet similar when reading the PDF.

Thanks for the suggestions – when are you planning to buy some 2SKs? Login or Sign Up.

I will try to get a load of s before there all gone
