빈자의 마크레빈슨 JC-2 프리앰프(클론) 소개 | 오린이를 위한 DIY 오디오 제작 책소개

JC-2 Parts List Finished Product ------------------- I receive a certain amount of commission for products tagged with "FLYNUT" as part of the AliExpress Affiliate Marketing activity. 0. TransAudio The R-core option appears to be new, while the M-core appears to be used. It looks fine if you just apply thermal grease to the JFET and bundle it with shrink tubing. https://s.click.aliexpress.com/e/_omD... 0-1. This is a TransAudio product... It supports balanced output, has an R-core, and is sold as a JC-2 Max. The TransAudio product looks good, with no coupling and separate power supply and left/right outputs. It has a DC servo... I even heat-shrink-wrapped the JFETs... It seems to be fine. https://s.click.aliexpress.com/e/_olv... The TransAudio product seems to be one of the better ones sold on AliExpress... DIY -------------------- 1. Preamplifier Transformer + Smoothing Circuit + EMI Filter Board | https://s.click.aliexpress.com/e/_okF... A 25W model is sufficient. It eliminates the need for complex grounding and makes voltage settings easy. Preamplifiers don't consume much power, so choose an appropriate one. Large transformers are actually less effective due to inductive current, which reduces noise, so smaller ones are preferred. 2. Audio Capacitors | https://www.powerfulsound.com I personally don't have any replacement parts for the JC-2... They all appear to be in good condition. 3. 3mm Nut, 10mm Support | https://s.click.aliexpress.com/e/_oom... 4. 3mm Hexagon Socket Button Round Head Screws (M3x3mm, M3x6mm) | You'll need 3mm and 6mm. The 6mm is for securing the chassis, and the 3mm is for securing the board. I'm using the 10mm support... https://s.click.aliexpress.com/e/_oFQ... 5. Amplifier Kit | MARK JC-2 | https://s.click.aliexpress.com/e/_oov... 6. Case | Coldmund | https://s.click.aliexpress.com/e/_oFI... The case includes an amplifier... Just remove the existing board and use it... The price of the case is not much different from the finished product. However, you'll need to re-drill the board support holes... Since the board is different. 6-1. Finished product with case mark JC-2 included | https://s.click.aliexpress.com/e/_oBP... This model has a coupling... You can choose according to your preference... 7. Signal wire | UL 2547 28AWG 2-Core Black | https://s.click.aliexpress.com/e/_oES... Two-wire signal wire 7-1 Signal wire | 1 UL 2547 28AWG 1-Core signal wire + shield | https://s.click.aliexpress.com/e/_oC0... 8. Power wire | Silicone wire | https://s.click.aliexpress.com/e/_okI... Convenient because the insulation doesn't melt when heated... but a bit expensive. 9. Fork Terminal 1.5-3, 2.5-3 | https://s.click.aliexpress.com/e/_ooe... Terminal work makes disassembly and assembly easier. 11. 6.3mm Female Terminal, Shield | https://s.click.aliexpress.com/e/_oDT... Convenient to have as a set. Used for noise breaker. 12.
