Pure power - Excellent audio performance Pure power - Maximize equipment performance. 2022.Oct 23, 2018 - The Schematic Diagram is a basic MOSFET amplifier. Output power is 100 Wrms under 8 ohms or 160 Wrms under 4 ohms with distortion is 0.001 %. The DOD Gunslinger's Mosfet circuit clips at a gradual, steady rate when overdriven, offering clipping properties and harmonics similar to those from preamp tubes in a guitar amp. ... - Mosfet Distortion Circuit - Independent Gain, Low ...All the part names for which the file mXwvryv.pdf is a datasheetFor other applications, like a Peltier Element, the 2SK170 circuit is better, because a Peltier Element delivers quite some current even while its Voltage stays low (below 100 mV). At 200 mV the 2SK170 circuit draws already too much power (about 14 mA). Here my measurements of the two circuits:Modern JFET (and some other) noise measurements. This investigation started as my attempt to find a replacement for one of the lowest noise JFET's out there - BF862. It was a wonderful part designed for AM radio front-end.

I have attached another variant of the circuitry for those that are interested in this topic. The changes I have yet to get around to is to replace all the carbon film resistors with metal films from the KOA MF/MFS/RK series, replace the FETs with matched 2SK170's, while getting rid of that noisy TL022 with an OPA2227.Most of the condenser microphones under $800 use the 2SK170 JFET, a low-cost, general purpose amplifier that can sound good when configured properly. But it usually used in circuits where its very high input capacitance (Ciss, 30pF) acts like a hardwired pad: it reduces the mic's sensitivity, which effectively raises the mic's noise floor.Search: J310 Substitute.

Today we're going to review their V6 Vivid Opamps, priced at $85-$145. Mar 13, 2019 · Recently we have noticed many low cost "Toshiba" 2SK170BL and 2SJ74BL in the market. Otherwise, a reliable way is to use ohmmeter to measure the resistance between drain and source. Genuine 2SK170/J74 has a resistance of 50 ohms or below. Fake ones have resistance over 100 ohms. It was heard that the fake ones were remarked from 2SK246 /J103. But when these FETs are also out of production ... The last time I saw that done was Craig Connolly's last Neotek release with 2SK170's fets used in place of the usual low noise bipolar 2SD737's. It did raise the noise floor as those bipolar parts are .5 nv noise, the jfets are all 1 nv or more for the 40 volt parts. A very high input impedance is one benefit of the jfet frontend.I f you are looking for alike VGS to have dc settings right probably 2sk170 may be a good substitution indeed.

This is in a pioneer sa900 Sorry, still a little Greek to me.The LSK170 is a substitute for Toshiba's 2sk170. Toshiba provides lots of information about the 2sk170, but Linear Integrated Systems provides little detail about their LSK170 replacement. For example, look at Toshiba's plot of voltage-noise vs drain current: the curve goes through 0.9nV at 2mA, which is the only point provided by Linear Systems.Re: U87Ai vs. U87: What's Really Behind The Difference in Sound? « Reply #22 on: January 02, 2014, 07:14:37 PM ».

You shouldn't follow the PCB silkscreen marking when using 2SK170/2SJ74 as replacement for the 2SK389/2SJ109. The pin-out for the 2SK170/2SJ74 is DGS (as viewed from the front, pins pointed down), whereas 2SK389/2SJ109 is DGSXSGD (X is an unused substrate pin).A Vari-mu compressor really only needs one dual triode. And a single 12AX7 (dual triode) is capable of being a completely useful mike preamp. And the U47 only has one tube device in it, but people seem to like it anyway. I don't think it's a good idea to insist on a lot of parts in the box to justify its price tag.that of high-IDSS 2SK170's, so at the same drain current the white noise will be the same. The 2SK369 has a higher Yfs and its white noise will be lower. It is remarkable, though, that the BF862 achieves the same Yfs at a third of the capacitances of the 2SK170. That's why I referred to the Toshiba datasheets. The BF861 too seems2022 popular Related Search, Ranking Keywords trends in with 2sk170 2sj74 replacement and Related Search, Ranking Keywords.

Thank you!The RIAA-equalization is done in quasi-passive style in form of a shunt network at the drain of the input stage cascode J1/J2. The signal is then taken from the source of the current source J3/J4and coupled to the output through a buffer stage. The ultimate solution would be disassemble the capsule, cut off the internal FET and instead, use 2SK170, selected for high transconductance. I will probably have to order some Panasonics and play with them. Tomorrow I will start serious listenings, measurements, tweakings, recordings, etc.This is an internet resource for those interested in guitar amplifiers, vacuum tubes, and design tools such as SPICE modelling.

The changes I have yet to get around to is to replace all the carbon film resistors with metal films from the KOA MF/MFS/RK series, replace the FETs with matched 2SK170's, while getting rid of that noisy TL022 with an OPA2227.Amplifier Is class A and deliveres from 10-30watts RMS depending on Supply voltage.

By all accounts it was wildly successful, and thanks to the decision to put the K170+J74 circuitry on an interchangeable daughter board, it's easy to compare the Nelson Pass original (WITH K170+J74) versus the legion of replacements (WITHOUT K170+J74). Compared to 2SK170 or 2SK370, the 2SK371 has a little bit more noise, a lot more gain, and has no P-channel complement. The Idss grades span different ranges too. In some less critical circuits the 2SK170 or 2SK370 may be substituted with the 2SK371, but tor all AMB projects that use these JFETs, the 2SK371 is not a suitable replacement.v2tay Step 3: Import Your File.

It may not be recommended for new designs, but the replacement, the 2SK880, is not through hole, it's surface mount, and that would mean redesigning the PC board.

However, the package is not pin-compatible with the β22 PCB. I don't recommend the use of any adapter boards. The matching between the two JFETs within the 2SK389 is not as good as two carefully hand-matched 2SK170s.Most of the condenser microphones under $800 use the 2SK170 JFET, a low-cost, general purpose amplifier that can sound good when configured properly. But it usually used in circuits where its very high input capacitance (Ciss, 30pF) acts like a hardwired pad: it reduces the mic's sensitivity, which effectively raises the mic's noise floor.The original compact K47 condenser microphone.
