March 24 2021, 13:10. The article describes the design and the performance of a high-quality DC-coupled all-JFET amplifier. The circuit was inspired by John Curl and Erno Borbely designs and was built with readily available JFETs from Linear Integrated Systems (Linear Systems). The input stage is the complementary JFET differential pair, the Borbely EB602/201 Analysed XEN Audio October 2017 Background Around 2004, Erno Borbely published his design of a Single-Ended All-FET Headphone Amplifier, the EB602/201. This is essentially based on his previous hybrid headphone amplifier, using a triode tube N-JFET long tail pair as input stage. This in turn drives a single P-channel 2006-02-04 6:30 am. #6. Re: Re: Has anyone used Erno Borbely EB-201/168. lineup said: As usual when using fully symmetrical all JFET amplifier design. problem is finding complementary JFET. If you do not find any nice P-JFETs to match your N-JFETs. your amplifier will be highly un-symmetrical. Yes that is correct.Har fulgt med på Erno Borbely siden jeg ble gjort oppmerksom hans konstruksjoner fra tidlig -90 tall. Har en uferdig Servo-50, klasse- A sluttrinn, ble litt for vanskelig for meg rett å slett. Krevde en del mer måleutstyr enn det jeg rår over.

Erno Borbely shares with us his all-FET audio amplifier design. Following the original introductory "JFETs The New Frontier" Part 1 and 2 articles published in Audio Electronics - which we also include in this online post - the follow-up article focuses on DC-coupled amps.
