The 2N k3a0 the gate on right pin when viewing the flat side of the package. The maximum gate voltage relative to source or drain on the 2N is only half that of the 2SK30A; 25V compared to 50V.
This shouldn’t be a problem in this circuit since the highest voltage in the circuit is 9V. The most important characteristic now is how much affect the gate voltage has on the current flow through the channel.
We can get a rough idea dataheet the operating range for a given gate voltage by looking at the channel current vs. 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.

If I were building this circuit, and I had the 2N available, I’d give it a shot. With the switch closed the total parallel capacitance is 0.
The values in the tone stack are then pretty close to the tone stack used in the “Tone 2” position on the FY The mid scoop is pretty extreme.
The tone stack forms a datwsheet of RC notch filter.
The 22K resistor and the 0. Datasheeh cutoff frequency for the low side is Hz, and the cutoff frequency for the high side is Hz. Not much of a notch there. Now, when you flip the switch the two capacitors in parallel add, forming an effective capacitance of 0.
The low side cutoff is now about 60 Hz.
That’s a pretty big chunk of the mids. To get the cutoff back up to Hz while leaving the 0.

You should be able to get a reasonably decent tone control by replacing the 22K resistor with a combination 3. Try clipping the pot and resistor in before soldering it up, just in case I’m way off base here. Help FAQs Go to top. Advertise on the most comprehensive and widely viewed musicians’ website.
