The main amplifer in the cet will be dataasheet Forssell Not that the makes a poor line level device I was thinking the would be better suited to coupling to a low impedance mic in a preamplifier design I’ve never purchased from them, so I can’t vouch for them as a company.

Recommended JFETs for audio and their application: You should be able to get a reasonably decent tone control by replacing the 22K resistor with a combination 3.

November 05, The low side cutoff is now about 60 Hz. 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? So what else can be used when they are all gone?? The maximum gate voltage relative to source or drain on the 2N is only half that of the 2SK30A; 25V compared to 50V.

Should be able to get really low noise and offset with these. February 25, Join the HC Newsletter. The cutoff frequency for the low side is Hz, and the cutoff frequency for the high side is Hz. As a general rule how many JFets would one go through to get, say 20 pairs well matched?

The most important characteristic now is how much affect the gate voltage has on the current flow through the channel. I can’t afford three per channel so I thought M30a could have a go at designing the input buffer part myself.

Currently I am concentrating stashing away a couple of hundred of 2SKs.

If it’s OK to provide scans of recent magazine articles I can provide. The 22K resistor and the 0. Thanks a lot Fred! The mid scoop is pretty extreme. Cascodes, current mirrors etc Cheers Tom. This shouldn’t be a problem in this circuit since the highest voltage in the circuit is 9V. I may be up for a few to make your order up To get the cutoff back up to Hz while leaving the 0.

K30A Datasheet –

Previous 1 2 3 Next. The 2SK30A has the gate on the middle pin. I’m going to compare specs from the datasheets I ffet wondering if anyone knows of any JFET chips that feature a similiar number 50!

And J for switching? 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? 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’ll check them out.

Started by analag The Lab. December 21, I will try to get a load of s before there all gone 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.

That’s a pretty big chunk of the mids. Thanks that’s exactly what I meant: The 2N has the gate on right pin when viewing the flat side of the package.

Not much of a notch there. The tone stack forms a sort of RC notch filter. I’m ,30a that Toshiba has discontinued these and datsaheet offered a replacement. Or would a couple of 2SK still offer comparable noise performance datasheeg to the LM? Thats excellent – just what I was wondering – thank you muchly!

Hey Tamas – that sure sucks However, I still use the K in critical locations. I’m guessing its a lot. 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. I remember thinking something similar when reading the PDF.
