You should be able to get a reasonably decent tone control by replacing the 22K resistor with a combination 3.

I’m going to ddatasheet specs datazheet the datasheets To get the cutoff back up to Hz while leaving the 0. Thanks a lot Fred! I was thinking the would be better suited to coupling to a low impedance mic in a preamplifier design 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 will try to get a load of s before there all gone 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. Fft by analag The Lab. That’s a pretty big chunk of the mids. As a general rule how many JFets would one go through to get, say 20 pairs well matched? Now, when you flip the switch the two capacitors in parallel add, forming an effective capacitance of 0.

February 25,30a Thats excellent – just what I was wondering – thank you muchly! Recommended JFETs for audio and their application: 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.

The 2N has the gate on right pin when viewing the flat side of the package. I’m not asking for you to share any precious circuit diagrams, just curious what other features you have added?

Fred if I may be so bold – I have been looking at your schematic and was wondering adtasheet different the s are that I have?

December 21, I was wondering if anyone knows of any JFET chips that feature a similiar number 50!

Not that the makes a poor line level device The mid scoop eatasheet pretty extreme. The low side cutoff is now about 60 Hz.

Not much of a notch there. Or would a couple of 2SK still offer comparable noise performance compared to the LM?

If it’s OK to provide scans of recent magazine articles I can provide. The tone stack forms a sort of RC notch filter.

The 2SK30A has the gate on the middle pin. Try clipping the pot and resistor in before soldering it up, just in case I’m way off base here.

I guess I might be able to swing a hundred This 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.

I’m bummed that Toshiba has discontinued these and not offered a replacement. Thats great stuff Tamas – cheers! Started by beatpoet Brewery.
