[轉貼] 我把RWA AK380amp拆了
手欠，我把RWA AK380amp拆了，真相竟然是用GOOGLE搜吧就能搜出來... 那電池好像快要爆了 RWA六年前已被我blacklist，永不再買。 原來erji有條feed討論，我send去mod之前都冇睇過，其實我唔明強國巴打up乜，意思係咪又spin緊換少少嘢收咁貴好過去搶？ 做咩咁多手 咁人哋都要research cost嘅{:1_245:} 本帖最後由 nanaholic 於 2017-6-7 21:51 編輯
吓？RWA一向都有寫改咩㗎wor，大陸仔發現新大陸？

RWAK380AMP Modification Details
- Add 25x additional (super-low ESR) capacitance to headphone outputs stages’ +/- voltage rails.We hard wire it to the PCB via short, high-purity Cardas Golden Section Litz copper wiring.This enhances the headphone output stages to provide high peak output current when needed.
NOTE: 25x added capacitance is NOT a typo – there is only a small amount of capacitance on the voltage rails of the headphone output stages, and we use energy-dense, super-low ESR capacitance to strengthen the voltage rails considerably.
- Add 25x additional capacitance (super-low ESR) in parallel with the battery via short, high-purity Cardas Golden Section Litz copper wiring.This enhances the internal battery pack’s ability to provide high peak output current when needed.
- Hard wire from the 4-pin BAL input pins directly to volume control IC via short, high-purity Cardas Golden Section Litz copper wiring (bypassing ribbon cable and connectors)
- Hard wire from amplifier output stage directly to 2.5mm TRRS BAL headphone output via short, high-purity Cardas Golden Section Litz copper wiring (bypassing ribbon cable and connectors)
tl;dr 咁人哋真係講到明係換幾粒電容同加幾條電線之嘛 {:6_134:} 本帖最後由 jaffeinism 於 2017-6-8 07:33 編輯
法國大餐{:1_340:}
呢三粒似係蘇聯仔flim cap, USD1.5/pc
