![]() The ‘596 features comparatively low Idss. The point of the exercise is to find a use for the 2SK596S JFETs I just bought and characterised (and indeed put on sale here). The major effect is differences in nominal transconductance affecting the gain. I simulated this design with various JFET models and they all give broadly similar results. The gain of the circuit is somewhat dependent upon the input impedance of the mixer and with R7 at 47k, gain is about 15.5dB. If you further increase C3 to 1nF, the upper -3dB point will reduce to about 14kHz. ![]() Note that the capacitor in the Zobel network (C3 above) has been increased from 220pF to 680pF. This simulates with a -3dB frequency response of 18Hz to 21kHz. Alex also mentions adding source resistance to Q1 and Q2 to reduce the gain and series resistors in the output lines to further reduce the likelihood of oscillation in the cable between the preamp and the mixer. Now, the high frequency response of this design is theoretically 3dB down at 25MHz so we definitely want to incorporate some roll off. If we increase the value of C1 and C2 to 22nF and increase R1~R4 to 3.3 MOhms, the -3dB point falls to 22Hz, which is more like what we would want. Therefore, the input signal sees a high-pass filter with a corner frequency of 1/(2 x pi x R x C) = 482Hz, which is considerably higher than 20Hz. input resistance and 220pF in series with 220pF to give 110pF input capacitance. If we lump all the input resistances together we get (R1+R3) || (R2+R4) to give 3MOhms a.c. Each side of the input signal is going to see a low pass filter formed by the input capacitor and the input resistors in parallel. This directly contradicts Alex Rice’s assertion that the frequency response is down by only 3dB at 20Hz. ![]() The above circuit simulates with a lower -3dB point at 2.2kHz and the output is down by 41dB at 20Hz. ac dec 20 1 20Meg to give a small signal response from 1Hz to 20MHz. Note: Please read Phantom Piezo Preamp revisited for updates and corrections. We take our output from the differential voltage OUT+~OUT- which is approximately what the high-impedance differential-input-stage of the mixer-preamp will see. We’ve left the Zobel network out because we want to see how the circuit simulates without it. Q3 is replaced by a 1mA constant current source The input is an ac voltage source R5, R6 and V2 represent the phantom powering circuitry in the mixer and C3, C4 and R7 represent the early part of the input stage of the mixer. I simulated the design in LTspice like this: It seems obvious that the value of C2/C3 is really rather low and therefore the low-frequency response of the above circuit is not going to be very good. Now I’m no expert at analog simulation, but I have played fairly extensively with LTspice and the above circuit does not appear to work. Alex Rice claims that the final design evolved as a result of “ a lot of fiddling around with circuit simulators and breadboarded prototypes.” R5 and R6 provide a little negative feedback and R4/C1 forms a Zobel network to reduce high-frequency ringing (oscillation) in the cable. R5/R1 and R6/R2 bias their respective JFETs. Q1 and Q2 are cited by Alex as a matched pair of N-channel JFETs with Idss 1-2mA and that Q3 should sink 1mA, giving a 0.5mA bias to each of Q1 and Q2. Here’s the schematic of the original design as reported by Zach Poff: Update: Phantom Piezo Preamp modules are available for purchase in the shop here.Ī few years ago, Alex Rice put a design up on the internet for a phantom-powered JFET piezo preamp. ![]() Update: Please see also Phantom Piezo Preamp revisited ![]()
