- #43 [唐吉訶德], 12-06-11 16:31timtube hing,
ECC85 是否特性相容 ECC88?
為何用ECC84 是"brave" enough, 有何高見? -
- #44 [timtube], 12-06-11 17:32Both ECC84 and ECC85 are NOT compatible with ECC88.
Just as ECC81 and ECC82 are NOT compatible with ECC83.
The differences in spec are significant(e.g. ECC84 has only 50% of the transconductance and 70% of the gain of ECC88). The tubes would clearly not operate as per the circuit design.
But I have seen "brave" people using ECC81 and ECC82 to replace ECC83 and sound came out from the amp.

$300 係多年前了,而且好雞聲吓,亦好殘吓喎,我都有一堆,狀態不佳下,輸比 ECC84好遠
如狀態好,用在後級驅動都 ok - #48 [rcwy], 12-06-11 21:31Substitutes for ECC88/6DJ8:

唔 out 呀! 雖然有人賣四,五,六百一對, 但我仲賣梗二,三百.
二,三百一對膽, 你想有幾好聲? - #50 [tubediyer3], 12-06-12 02:35唐吉訶德兄,
我借2支你玩玩.結果話我知. 其他50年代mazda等, 揾到再話你知. 一齊了解下. - #51 [tubediyer3], 12-06-12 02:36肥圈德國粉字版.

It is a great news to me. You're a collector of ECC84?
I believe ECC84 is a good tube for you when diy your own gear.
I'm now still collecting all chings comment over this tube. I'm not "brave" but looks not much negative reports from chings till now.
PS: kc ching, if those tubes you're selling are in good condition, I feel high interest too. In the past, I only trust Peter who is selling tubes in Review33 for years because he is the one honestly offer us the exact condition of tubes when he sell them. He never tell me those tubes are in good condtion when they already looks poor and smokes & marks in tubes. At the meantime, he offer his precious advice during our past conversation. I respect him as a honest person here.
BTW, his selling price is my guildline too.
Regards
最後修改時間: 2012-06-12 07:09:18 - #53 [timtube], 12-06-12 08:55Actually if you can DIY and able to rewire a tube, the E182CC/7119 may work as a sub for ECC88.
People use E182CC to replace 5687 simply because it has the same pin-out, but it is actually closer to ECC88 compare to 5687 electrically. You may, however, need to have higher filament current supply. - #54 [philiplee], 12-06-12 09:44Kc hing, 你嘅市場價格好 out 喎!

早幾月前 我賣 一百 都冇人過問 . - #55 [唐吉訶德], 12-06-12 09:50philiplee hing,
可惜!我可能忽略了!Amperax 6922 賣$100,真吸引人!
蘇州過了嗎?
重溫 2nd market, US made, Amperax JAN 6922,賣 $800/pair, 未找到你 $100 條 thread 喎!
PS: 你的照片又清晰,又漂亮、質感又好,可否分享如何拍攝?
Cheers

我照相是初哥 ,見笑 ,
金腳 USA 6922 就是聲音平平 ,有機會見到送你 兩支 . - #57 [唐吉訶德], 12-06-12 13:54>>唉!都是市場價值問題,畢竟玩膽是「小圈子」的玩意吧?!定律就係無人玩就無廠做,終有日「天價名膽」都會用完(除了個別收藏家外)要不就只有選用現今剩餘的幾間的新制品了!x100
>>石機玩得好都好靚聲。尤其用平行。x100
基本上,以我愛膽二十多年的膽迷來說,真有些無奈!
近年我都是輾轉在膽及石的路上,對膽始終有無限情意結!所以更留意近年有用代用膽的玩法。
但我會留意技術指數是否可用,而不希望一下子蓋棺定論!希望找到一片新天地!
有些時候是發覺枉然的,又需反覆找師兄求証
如之前 E80CC替代 12AU7,真的頗具突破性,噪音、音色、耐用性都極出色,奈何燈絲流相對 12AU7 大許多,導致工作電壓拖低20-30%,如何能作準,又令電源牛增負荷,最後只能間中使用,結果徒然
這次買了 ECC84,替代已力衰之舊膽,無論各方面表現均理想,但又擔心有負面因素,所以希望各方師兄分享意見
之前有用 6N1P,各方面均不理想,咪高峰效應更差,放棄了!
Amperax US, Globe 及 Holland 均表現一般,可作砲灰膽使用,但最近不便宜!
如果 ECC84 能用,對我能力有限的用家來說,許或有機試玩 Mullard, TFK 等名廠,是福氣了!
當然,仍一直擔心會令機器維修!勇敢未必,魯莽是肯定了,愚蠢是未知........... haha
結語﹕諸君了解小弟為何取名"唐吉訶德"了嗎?

Try 6211 or E80CC/N. Its filament current is the same as 12AU7. - #59 [fungfung334], 12-06-12 15:30好明白唐吉訶德兄的心情。用有限的(錢)來玩名膽實有其極限,而且名膽日漸難求下,我等「有限公司」要買名膽實在可一不可再,自然希望能夠找到其它較有水準的「便宜膽」來替代吧,限於自己對電子知識淺薄,實不敢隨便使用「代替品」,愛玩物還不至於喪志,危機意識還是要有的。不過,在這裡也不乏有心能人提出有用見義,都是值得參考和選擇的。

It has the same pin-out as ECC88 and therefore not adapter or modification is need.
