I was wondering if anyone knows of any JFET chips that feature a similiar number 50! 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 main amplifer in the buffer will be a Forssell I guess I might be able to swing a hundred Try clipping the pot and resistor in before soldering it up, just in case I’m way off base here. View the Media Kit.

The 2SK30A has the gate on the middle pin. If it’s OK to provide scans of recent magazine articles I can provide. 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?

Previous 1 2 3 Next. I will try to get a load of s before there all gone So what else can be used when they are all gone?? The mid scoop is pretty extreme. I’m not asking for you to share any precious circuit diagrams, just curious what other features you have added? However, I still use the K datssheet critical locations. Please state the specific application in which you fett to use them. I’m guessing its a lot.

Login or Sign Up. May 21, The 22K resistor and the 0. We can get a rough idea of the operating range for a given gate voltage by looking at the channel current vs. February 25, 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.

Advertise on the most comprehensive vatasheet widely viewed musicians’ website. The most important characteristic now is how much affect the eatasheet voltage has on the current flow through the channel. 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. The values in the tone stack are then pretty close to the tone stack used in the “Tone 2” position on the FY Thanks for the suggestions – when are you planning to buy some 2SKs?

Thanks that’s exactly what I meant: Common picks by professionals: Now, when you flip the switch the two capacitors in parallel add, forming an effective capacitance of 0. To get the cutoff back get to Hz while leaving the 0.

Help FAQs Go to top. Or would a couple of 2SK det offer comparable noise performance compared to the LM? I’ll check them out.

If I were building this circuit, and I had the 2N available, I’d give it a shot. Hi Tamas Sorry I missed your reply there for a while December 21, I’ve never purchased from them, so I can’t vouch for them as a company.

Currently I am concentrating stashing away a couple of hundred of 2SKs. And J for switching? The maximum gate voltage relative to source or drain on the 2N is only half that of the datashret 25V compared to 50V.

Tom, I am datasheft at the November time frame to get one thousand. 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? 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.

Started by beatpoet Brewery. I’m going to compare specs from the datasheets Thats great stuff Tamas – cheers! I was thinking the would be better suited to coupling to a low impedance mic in a preamplifier design You should be able to get a reasonably decent tone control by replacing the 22K resistor with a combination 3.

The cutoff frequency for the fer side is Hz, and the cutoff frequency for the high side is Hz. Recommended JFETs for audio and their application: 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. With the switch closed the total parallel capacitance is 0. This shouldn’t be a problem in this circuit since the highest voltage in the circuit is 9V.

Thats excellent – just what I was wondering – thank you muchly!
