Like! I want to pick up fixing electronic and building my own stuff when I have more time...what's the best way to learn if I know nothing at all? Even my soldering skill sucks big time....haha

Tsang sir is indeed a real gentleman who is willing to share his Hi Fi knowledge to all of us.

He also shares many useful links to me as a layman to improve my limited technical know how.

My salute to him for his passion and dedication to our Hi Fi community and journey. We are fortunate have him to revive our vintage toys..

Highly appreciated to Tsang Sir!!!!

好心你們啦, 曾生假假地都工程師, 幫網友修機純粹係助人為本, 興趣咋, 老實講真正靠修機糊口的, 整好便算, 邊有咁好心機同你跟個線路出黎, 仲跟埋其它唔妥之處, 找曾 Sir 修機, 唔該都冇聲, 太沒禮貌了.

The AU-D9 is back ! Take more care to fix this time.

(1) changed the circuit to better match to use wide bandwidth power transistor

(2) replace all old leakage driver (A968/C2238)

(3) replace leak ecap to MKP as much as possible

(4) Find out more cracked old soldering and fix them (terrible at the Preamp broad)

Here are the photos for sharing.

- Modified the circuit
