there are some material used in some period, they melted

may be it was that

從你的相片我感覺到 你的wheel 是有點古怪的 the edges deformed kind of round..May be that was the photo angle or. Lighting.. But not seem normal..May not be original.. Guess .

And now u said it is softened

But it does not matter... As u going to change it

謝謝Haha師兄回覆，我発現橡膠輪已極度軟化，所以剛在ebay訂了一個新輪替换。

擔心有傷害的就走去汽車器材舖買支3m嘅橡膠清潔噴劑

心急嘅就隨手攞支70%酒精(me)

請問各位師兄,如果部R&R機冇開一段時間,發現個橡膠導輪變成立痴痴,應該用冇清潔呢?

This is a Telefunken M36 military recorder, from 1971.
It was designed for use in tanks, planes, U-boats, trucks,...

Hifi 朋友門，各有各玩，最緊要自得其樂。

不用客氣不要客氣

大家玩玩具分享

呢個話題真係不錯專業器材在家使用

例如那些emt turntable.. 電台級別 reel. To reel..studer Etc.. 我都 有固執的偏見 放棄haha
.. 多出嚟嘅功能, 甚至啲蟹動作的優越性 and build quality, for me it is no Value for my home use

佢哋quality 真係值得appreciate

最近包裝起我啲玩具.... 搬搬抬托 總數幾tonne 的東西... 耐心有點微笑.. 真係好彩上年朋友幾乎送 emt 950 to me.. I refuse it.. 有很開心好彩冇留起嗰啲大件嘢.. 十年八年前仲幾好價錢放走 haha

專業東西.. 我只會真心建議 technics sp10 適合家中使用, 其他的都係一個擁有感... 這是我個人以我的經驗分享

有時都會心思思 見到價錢唔貴嘅 studer 不如又買多一次嚟玩下啦... 但係 我克服到這種 購買慾, major 是我好了解自己嘅應用, I waste those Pro machine,


大喇叭的例子... 有趣的



hey 95 Hing

from your exp. dynamic and definition... which NON Pro machine u feel it match some of the Pro MAchine ?

Lets B77 High Speed 2 Track ... seem to be one of them

Haha

Haha大哥
The reason why I ask is just that it is so easy
To tell the differences if u play on one system.
Especially if you compare professional machines against domestic home use hifi
Models. The dynamic and definition of the music could so easy to tell .
It is recommended to those 發燒友have the luxury to play music on large speakers especially on 爆棚發燒音樂，or classical symphony excepts .

Not easy to judge

As my sensation does affected by the sense of ownership and the sense of touching


For hifi.. If I have to judge Which is better.. I only trust my truth blind test and the first feeling without knowing touching what I am listening to


I guess when open a Telefunken.. And deeply impressed by the real things, the way they do the switches, touching them.. Feeling them by my finger.. . Etc.. ... From that moment.. I will Feel everyhings from that machine is better...so that judgment shall be bias by knowing it

From the look of many photos, especially internal .how could a person not feeling the Telefunken is a better machine and not affecting our hearing perception?

Hifi quality perception... Sense of ownership is a big part

950347

am totally not sure.......as it always set up with different set of hifi system

never use them within the same system at same time

but i do prefer the sound from a cheap sony and the sony TC 7750 , both seem to sound more airy and 3D

dynamic wise the X2000

tonal wise Sony, it is a personal preference

for the life of tape ... especially some old tape, Revox seem better.... as when we play an very old tape..trace of magnetic powder may fall off...... X2000 seem not do good in term of this aspect , may be it is a set up issue

Revox may be better for someone who trend to prefer "slightly " meaty sound Vs the sony

as i use them for a very Casual Background music listening

but there was some super impressive moment from that Sony.... 3D sound stage..etc... but never had that from the Revox or the teac ( both are very good , just do not have that super impressive moment ), that can be heard from some live jazz recording

if i really have to make a choice...i would go for Revox, as it is really many resources for trouble shooting and not require pro level of workmanship ..i may like to keep a few A77 to mess around with it

for my way of using them ...A77 is sufficient , bypassing the amp section seem not difficult

i love to try some telefunken one day , may be their amp section...i do not feel the need to change it

my vision of R2R, somehow every similar to LP with different phono stage for tonal preference

all i need is a reliable transport which easy to work and service , something not too heavy..haha

Haha 大哥
Among all the recorders you have owned
Before, which one you found the best sounding machine ?
My Choice is the B 77 high speed.
For normal speed 7 1/2 , telefunken m12a is
The best sounding machine That I had used .

I had 2 prosummer type of Japanese machine

A teac x2000, and sony 7750 (2 tracks)

I also have a few 3 motors consumer unit from teac and one akai

Single motor unit Sony too

Revox A77 b77 and A700

In term of serviceability, teac consumer machine is quite easy to work with,

Teac X2000 is quite difficult to work with, it certainly need pro level of troubleshooting skill and soldering skill, not quite recommend to buddy

Sony Prosummer type, easier, some better expert advice is needed, pcb is easier to work with

SONY 377 TYPE OF single motor.. Great little machine, super easy to work with,

I never have higher model of akai,I have lower end model,, easy to work with and plenty of Troubleshooting tips around too

Revox are not difficult at all, parts is easier to find, service manual take time to digest and careful reading

A happy hobby consume quite a bit of time..

Obviously must be revox A77 and B77.
It is so easy to get help from forums when fixing the recorders, so easy to buy spear parts
And new parts from the internet.
I have no knowledge on Japanese made recorder, it would be easier for me to comment on Revox recorders. I had used a number of A77and B77 before and they were all sounding good , remember we are using
Swiss and German hand made appliances from the 70’s and 80’s. They were way better than others. Just like colour television in the 70’s,
We all prefer to have a German made than Japan made model , right !

Hi 950 hing


Do you have any chances compare some of those revox to studer? From an audiophile prospective how do those compare sonically?

Other Than revox, what u may recommend for a reel 2 reel newbie for hifi?

Serviceability is always an issue for many people who fear not to try..


Thx for sharing

Revox/studer
Revox C278 1/2 inch recorder

Many Revox open reel recorders are so good , like C270 to C278, full balance in-output. I enjoy so much with particular A700 , A classic for hi end stereo collector and audiophile.

專業嘅錄音機同埋唱盤

都有著一啲 令人提升使用感覺嘅 感受

超快嘅起動, 超級順暢立即嘅 brake

Mechanical 鏗鏘 令人舒暢嘅運作聲音
Etc...

All make people feel so much nicer...


還有很多設計.. Enable on the field service so efficient...


優質嘅使用feeling

我記得 但係忘記咗邊一啲錄音.. They use A77, crown 現場錄音嘅工具... Jazz.. 好好聽

始終咁多年完全冇去比較過 professional Machine to some Consummer machine for hifi listening feeling

呢十年八年 覺得 AB test, feel 好浪費時間, my time not justified for proofing which one is better..

As long as I feel happy with whatever I have.. I am happy


可以肯定.. Better tensioning mechanism better sound

Haha




Haha
