The Starter kit EB-604/410 line amp is a high-quality, low noise, low-cost all-JFET circuit, with onboard regulators. It is designed to work with 6−20dB gain. For gains up to 12dB, you can use single-matched JFETs (delivered with the kits). For DC stability, I recommend dual monolithic JFETs at 20dB gain. 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. Borbely har en klar formening om at Fet er bedre en Bipolare transistorer: 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.
