煲了機個鐘後，把常聽的cd用以試此老年dvd player， 結果是: 我可以把 cec player 收埋也{:1_262:}
兩者都是年事已高的player. Philips 已有差不多十年未用過， cec 則日唱夜唱，兼mod 左，如換iec 座及兩粒鍍銀fuse。前者讀cd健步如飛，後者，不用提。。。 菲仔multi player, C 仔獨沽一味。
兩者最大的音效分別是: 菲仔聲音較開放(硬朗d)，空間感較大及有股暗勁，並聽多d細節(突出d)，聽三角鈴的餘音及位置線條，正正正{:1_341:}。c 仔的聲較暖(音樂感?)和音像較暗。後來把菲仔的四隻foot 拆走，改承Harmonix金釘，聲音柔了些，多點音樂味。
尚有改造否? 有! 換支發燒fuse, 切幾塊銅片貼在四邊及低板，換cap (有C hing 提供意見及用料，再多謝了){:1_249:}
唯一的問題是間中skip trac 時喇叭發出一下"bok " 聲，有否高手指較?
学习了ching好手工！

why not connect the safety ground to chasis ?
what if changing the E-cap (i.e. HV storage) to a larger value (e.g. 120~160uf, 400/450v) ?
are u able to measure the ripple magnitude of the 5Vdc and 12Vdc ?

The dvd player itself has no safety ground connection (default).I have thought about adding a ground wire. For your other comments, I have not gone so far.{:1_256:}

Wow, I know about the cec laser head model but have no idea how good it is. Would try to fix/replace the rubber belt later.
