I'm DIY beginner and interested in this course.
Just want to ask what the output power of this tube amp is ?
and can it drive a floorstand speaker (89db) ?
Thx.作者: admin 時間: 2007-1-4 04:37
1W output, better to drive full-range speaker作者: steve148 時間: 2007-1-4 13:33 標題: Re: 搭棚初班 - 睡房/書房真空管後級DIY The output power is so small. How can I choose suitable speakers?
Is it any class to teach theory only?作者: siukee 時間: 2007-1-4 15:01
7,
I agreed, hard to integrate this into my system...
Treat this as an introduction class to bigger things (300B amp) to come.
can it be used as a headphone amp?作者: admin 時間: 2007-1-4 15:43
Theory is best to complement with workmanship so you can treat this course as a experiment course for your future assembly (300B, VT60, M3, etc....)
We also have some Full range speaker available later so you can match it with the amp作者: harrypoon 時間: 2007-1-4 17:19
Given this amp has its limitation, it is still chosen for this course. I believe there must be reason/justification behind the choice.
May be if potential participants understand the reason for choosing, they will be more certain about their participation.作者: admin 時間: 2007-1-5 11:18
樣品機已完成
modi Sir 希望可以令各參加者可以充分了解搭棚的技巧, 要注意的問題. 一套細細部的機比較容易做實驗. 所以大家應視這個是搭棚班多過後級班作者: tommy2047 時間: 2007-1-5 13:03
dear site admin
does the price cover the case of the amp? can the amp, without using a pre-amp, drive my old model of 3 ways KEF speaker? Thank.作者: modi 時間: 2007-1-5 22:09
大家可能覺得1W很細很細,但我可以話比大家聽,唔好睇小呢1W啊!
絕對足夠睡房或書房使用的!什至大家在睡房最大只會開到12點位置呢! 作者: admin 時間: 2007-1-6 00:54
tommy2047, yes case included. We can use it to drive KEF XQ5 (of course not very loud)作者: modi 時間: 2007-1-9 18:45
進行測試 作者: modi 時間: 2007-1-9 20:03
再發一張圖,大家現在是看不到遙控部份的,目的是方便大家參考,而遙控也會給大家參考的。作者: arthuryau 時間: 2007-1-9 20:52
can you provide the circuit for reference as I have some spare capacitors in home作者: siukee 時間: 2007-1-10 14:22
Modi,
Thanks for posting all the pictures, very informative.
Can you help? I would very much like to add a headphone scoket for use with my headphone? Can it be done?
恭喜大家完成了細膽機制作! 作者: siukee 時間: 2007-1-29 16:40
Hi Modi,
It was a hard fast and very enjoyable 2& 1/2 days. In the end we all had our amp on the system for listening....
Anyone who is interested in getting into DIY hifi (much more rewarding that buying the expensive models), this is a very good course to get on. I have zero expereince in anything hifi...and to have this amp in my hand at the end of 2 & 1/2 days was thoroughly exciting.
The goodthing was, we all had modification of our own and the course accommodated all our needs. I had installed a headphone jack (for my AKG 701) and upgraded to "black gate" capacitors....looking forward to listen this after running it in.
Next project....?
I did not test (distortion, signal etc), when can I do these tests and to finish off the remote control set up?
Good job and thanks

我在搭棚初班真是學了很多知識,我可以有信心做一部300B後級。
在1月28日我們幾位同學很努力做到晚上十二時才能完成我們的5687後級。
modi Sir 仍然堅持給我們時間去完成我們的作品。你仍然用你的專業精神去教導我們和測試我們各部後級的output, 失真和噪音。你更讓我們試聽各部機的音效。
modi Sir 的服務真是一流。在此多謝modi Sir。
下次我想參加CD 唱機的改良課程。
