<- 咁冇辦法,想換亞加力盤都係要問返原廠,有原廠 support 將來換咗盤萬一遇到轉速唔同咗都仲可以搵到辦法去解決。 - #50 [hahayanyan], 21-05-17 13:37#49
Good improvement? -

- #48 [長長影子], 21-05-16 22:56我其實一直以來都用好多 alpha gel,仲有測佢嘅 material properties 嚟做 simulation。
- #47 [hahayanyan], 21-05-16 22:35Somehow... We need to beleive those S/N ratio from the maker...
Haha
I have a project which need some alpha gel... Which was not that difficult to get thsoe from China... But not now..
Some of the off the shelf alpha gel mount seem applicable for hifi turntabe hobby too( as u mentioned... Rubber...), then lead me think of alpha gel.. And tpu.. Etc.. - #46 [長長影子], 21-05-16 22:11"影子兄,我都想車個啞加力來玩玩,可在那處定到?"
<- 我 wechat 原廠嗰個老闆(蔣先生)請佢幫我訂造,佢又肯喎,之前補錢 trade-in 支唱臂佢都好樂意,但發現兩個轉盤之間直徑有少少差異,最後要換埋驅動帶嗰邊嗰個拉輪先至 set 到正常轉速。 你嗰個唱盤係相同型號?
"Only for the oil..."
<- 同一情況只係比較油我諗都合理呱,但黏性低嘅油用起上嚟好似滑啲咁,其實容易流失壽命長短就比較難試。 唔同盤之間我諗冇得咁易比較。 - #45 [hahayanyan], 21-05-16 20:55What if, if it is a comparison with the same platter, same bearing.. Etc.. But different oil, the only variable is the oil .. For the performance indication of different oil...
Not for comparing which parts is better.. Etc..
Only for the oil...
Then someone then having a test disc for wow and fluttering test...frequency counter.. Haha but most of us do not having them... Haha.. May be an apps...
I would goes for... The oil with least wow and fluttering..provided it has a reasonable run down time... Haha but what is reasonable? .. Haha
Hope thsoe oil selections.. May have similar wow and fluttering.. Then easy to go's for the one with longest run down time.. Etc
some said...Acrylic having very similar physical property as the Vinyl material, which make it one of the sensible choices as a platter............. but is it truth ...apart from that belief ? providing some condition has been met.., that can be
interesting......is a platter which able to spin longer = better? seem not...
for the same platter...same..etc same +/- similar shape curve of speed..etc...... the oil which make things spin longer..., seem better without too much doubt

- #43 [長長影子], 21-05-16 20:41我以前有比較過兩個唔同重量但用同一個轉軸去做實驗,如果係要先維持同一轉速下睇佢可以轉幾耐先停,個盤重可以轉耐啲而轉速亦會比較穩定,我會覺得係同本身轉動質量比較有關係。 但我仍然選擇用比較輕轉得冇咁耐嘅亞加力盤,所以係咪轉得耐就最好,我自己就覺得冇咁絶對,當中仲有好多綜合因素需要去考慮嚟取自己認為最佳嘅平衡點。

###RIP LP 好處係錄嗰時喇叭可以唔發聲減少震動###
That is super truth... I suspect and beleive that it is so truth... The impact from the surrounding becasue of the sound wave fro mthe speaker to the LP playback.. Is huge... Somehow it make sense for having balance output from the cartridge abd having the table at the other room... Isolated from the main speaker.. Haha...
Dsp phase correction... Wish those obvious benefit can over come some digital processes... Which may take away some analog juice.. If any haha
Haha.. U talk about real ripping.. Things done beyond the level of common user recording.. Haha... Very common from the sense of 執靚 一幅相
Thsoe run down test.. Some lenco, well maintained one.. Not mine.. Able to go goes beyond 2.5 mins.. And some with renew bearing etc.. 5mins.... And with upgraded etc. 7 mins.. Haha
Would love to get some data from those massive micro table sometime from thsoe Mico users - #41 [rcywong], 21-05-16 18:52
黑膠真是百聽不厭。
- #40 [長長影子], 21-05-16 17:23"請問唱盤和唱臂的牌子是否 FFYX?"
<- 正是 FFYX。
"and the clamp is DIY too ?"
<- 石墨好難加工,喱個就算我有部小型 CNC 都 DIY 唔到,我用 Weizhi。
"我有啲朋友有啲tables 狀態好好真係五六分鐘都唔停㗎"
<- 我覺得同轉盤重量及動力慣性比較有關係。
"勁,成座airforce咁"
">> 大殺傷力重型武器呀!^^""
<- 但我喱部只算係粗嘢,啲細節位有唔少手尾要靠自己去執,潤滑油嘅問題係其中之一。
"Sometime.. Some table It may not be good.. Need to further verify the wow and fluttering... If so less friction and also very low wow and fluttering.. Then that is the good oil for that table"
<- 喱啲問題係可以用測試碟嚟試。
"What ADC is using? Any particular caution for ensuring a good rip?"
<- 我用 Mytek Brooklyn ADC (MQA-ready) 嚟錄。 RIP LP 好處係錄嗰時喇叭可以唔發聲減少震動,錄之前每隻都要先洗到乾乾淨淨然後逐隻碟跟厚度嚟調校對應嘅 VTA,錄成 file 之後仲可以 corr. 唱頭左右嘅對稱度及 response 同埋執走部份太明顯嘅炒豆聲。 我其實有好多隻白版碟,RIP 咗去嚟播放除咗可以減少隻碟及針嘅損耗外,又可以比 real-time 播放時用更好嘅 DSP 嚟做 phase corr.。 - #39 [hahayanyan], 21-05-16 11:10#29
I assume u rip the LP into digital...(if i rip any..., it will be only A to A ) haha
What ADC is using? Any particular caution for ensuring a good rip?
I guess some of us.. May love to do the same...

帶動式唱盤就容易測試,
甩咗條帶,用手轉一下,
正常分半鐘左右先至停,
一粒聲都冇的。 - 下一頁 (2 of 4)

if u take risk.. i make u one by our cnc shop....haha
if things speed goes wrong... , we can always adjust the sizes of the pulley at the motor sides... once and for alllllll
