Linear Systems Matched JFETs
Some lines might be available for back order. Before placing a back order, please make yourself familiar with how backorders work and note that we do not ship partial orders.
Product Details .
- Guaranteed authentic Linear Systems JFETs
- Matched to ±0.1mA (tested at 10V / 22'C and sorted into 0.1mA bins). For more information see our JFET matching information page.
- NP (LSK170/LSJ74) are ideal for a stereo BA-3, F4, F5, F5T, F6 and more
- PP (LSJ74/LSJ74) are ideal for Aleph J or BA-1 gain stages
- Please direct all technical questions to the Linear Systems JFET support thread
- Limit of 2 units per customer per month due to supply constraints. We want to ensure they all end up in the hands of builders who are going to use them for making projects, not hoarded or resold.
- If you need more than 2 for a particular build, please email firstname.lastname@example.org with details of your build. Our goal is to see the most amps actually built and shared with the community as possible.
- We provide these matched JFETs as a service to the do-it-yourself audio hobbyist community and it's important that we can always keep these parts in stock for small orders from hobbyists. Please keep this in mind when ordering large quantities. If you would like to order a large quantity, please check with us first via email to email@example.com.

Perfect matched transistor with a long lead time (6 weeks)
Already in use in my F5 with very good results
Measurement will come very soon online
I ordered 2 quads of JFETs. One was for the Ishikawa input buffer on my M2X and the other is for the Aleph-J that is under construction. The Ishikawa worked perfectly first time and when I measured loads the difference was below what my equipment could detect. The harmonic distortion of the amp was very low with the Ishikawa. Best of all I really like the way the M2X sounds. These are great. Thanks!
Great people, and excellent communication. Products work and they gave me personal help.
Very good parts. Nice to get the matched as well. Hope to be able to buy some more of the pairs, quads or octets. I was planning to build a few discrete JFET Opamps for my microphone preamp.
It's nice to have found a trustworthy supplier.
Pls. make sure that what you are selling also corresponds to the actual picture.
great product and fast delivered, recommended
matched very closely, excellent performing jfets, as good as rare Toshibas.
Very well matched N-/P- channel JFETs from LINEAR SYSTEMS. Fast delivery and well packed.
Great service as always!!!
