Does anyone has a copy of Ken Kessler's "Quad book"?

Quad FM tuners

3338 hing

Input sensitivity of 405-2 is 500mV

I used to had 606 2nd generation and 3rd generation. They were good to match my Denon pre amp and JBL speaker......^o^!

I sold the 66 pre and 2 pc 606 already long time, now only left the 66tuner ＞_＜!

My 405.2, very good sound really!

Dave

hi Dave,

sorry, I am not expert in electronic,
though I did the mod by myself,
I alsmost forgot how to do it again.

Probably some other web mate can help you.

One thing I can sure, sound can be improved
quite a lot without the Quadlink.

dave,

the caps on your 405-2 are quite new and little
mod has been done.
thats why you have no problem la.

But the vintage Erie caps on my 405 are original which are 28 years old. 巳經鞠躬盡瘁.

Dear Friends,

I have done it with a High Hand yo bypass the quad link, but compare to 405.2!!!!!

405.2 sure win on Vocal, if you have two to compare, it should be the yellow label is more better.

I using my M3 Kit with LP so i can tell to difference very much.

Just try.

Dave

Dave兄,
405.2黃色或藍色邊的聲音基本是接近的，主要分別是一對power管和水塘電容，如用BHC電容，聲會甜D；RCA或Mo記power管又唔同聲。但405.2期數又多，好難以此作準。

KL Hing,

我隻是灰色，人聲好嬌好透，我用M3 Kit 加 ASR Nini Basix 加 Lp 泥玩 Rogers 3/5A，個個話我頭重下面輕，但個人喜好！

但405.2真係好好聲，909 就！ 一言難以說之，新不如舊！

Dave

Dave Hing,

your 405-2人聲好嬌好透 bcos you have added Film Cap to the 水塘.

9系用料沒有4系列那泵n, 但移除quadlink後仍有脫胎換骨的感覺, 超碼開揚生猛很多.

3338 Hing,

But the Film Cap has been removed from the 水塘.

Yes, 移除quadlink後有脫胎換骨的感覺, 超碼開揚生猛很多 X 12. 但很Dimm, Pin point 唔夠，但音樂感好！

但音色，人聲，3D 感，始不及405.2，可能個人偏激，因從89年聽到現在才轉909。

但如你有機會比較一下就明我感受！

Dave

3338 hing,

Some high hand modify for me, and he gots quite alots of spare part of 405.2, even the motorola semi-conductor and others parts.

Maybe he can help you to make it alive again!

Dave

Dear all
My gears are 34+606 with KEF ls35a,very glad to meet Quad fans here,happy new year and Kung Hei Fat Choi!

SY Hing,

我部34左去摩，606好過909，但405.2 最正！

Dave

Dave 兄
Pls tell me the difference between 606 and 909,as my 606 has been used 17 years,may be it will be instead by 909.

SY Hing,

Never Have a chance to audit 606, but you can see what my experience now between 909 (by Pass Quadlink) and 405.2.

I prefer 405.2, more 嬌嫩欲滴好多，比起909 清爽, 力氣都比909大，反而覺得909好似無氣咁，又Dimm！,

But Now 909 is more muscial, so it all depends on your taste.

I am now swift between both amps for difference issue of LP and Cd to suit into my own taste.

dave

I am also curious of the 606's performance. I have only used 405.2 for a short while to drive my 3/5a but since the first minute using it, I am attracted to it. Very musical amp!
Apart from 606, I really want to learn more about the difference between 405 and 405.2, any comments from the current or ex-users who try both? Thanks.
