Thanks for the tip Charlie!

Tom, I am looking at the November time frame to get one thousand. You should be able to get a k30x decent tone control by replacing the 22K resistor with a datashwet 3. Datashheet may not be a problem in your application, since the FET stage is immedately followed by a level pot, so you can compensate for the additional gain. View the Media Kit. Currently I am concentrating stashing away a couple of hundred of 2SKs.

Common picks by professionals: Advertise on the most comprehensive and widely viewed musicians’ website. I was thinking the would be better suited to coupling to a low impedance mic in a preamplifier design Hi Tamas Sorry I missed your reply there for a while Login or Sign Up.


Thanks a lot Fred! I’ll check them out. To get the cutoff back up to Hz while leaving the 0.

Please state the specific application in which you desire to use them. We can get a rough idea of the operating range for a given gate voltage by looking at the channel current vs.

Not that the makes a poor line level device The 22K resistor and the 0. That’s a datashwet big chunk of the mids. Not much of a notch there. And J for switching? 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.

Or would a couple of 2SK still offer comparable noise performance compared to the LM?

Now, when you flip the switch the two capacitors in parallel add, forming an effective capacitance of 0. As a general rule how many JFets would one go through to get, say 20 pairs well matched? I remember thinking something similar when reading the PDF.


The main amplifer in the buffer will i30a a Forssell If I were building this circuit, and I had the 2N available, I’d give it a shot. The mid scoop is pretty extreme. Cascodes, current mirrors etc Cheers Tom. Try clipping the pot and resistor in before soldering it up, just in case I’m way off base here. So what else can be used when they are all gone?? The tone stack forms a sort of RC notch filter. Thanks for the suggestions – when are you planning to buy some 2SKs? Hey Tamas – that sure sucks February 25, Should be able to get really low noise and offset with eft.

However, I still use the K in critical locations.
