[#45] etsang3 修理好聲"山水"機一部    
ttvfwong hing,

I remember seeing one of its studio speakers...
The Radio People (TRP) owned a advanced wood work factory in Kwun Tong (the warehouse at Shan Po Kong) those days.
2 models of TRP Loudspeakers were manufactured. They were called Spectrum V and Spectrum VI.

Spectrum V is similar to LS3/5A, same size and same using KEF T27 and B110 units.

Spectrum VI is quite special. An Audax cloth soft dome tweeter at the top, 1 " inner face than the woofer face, gives very musical sound. 2 5" Audax driver unit for mid-low, one outside as normal and another one sits inside the speaker body, connected in reverse polarity, its output is 3" TUBED to an opening just below the outter one.
These produces a very lower freq. extension (transmission line effect), quick response with no coloration (each only 5" size) and rapid punch sound (The air in Push-pull zone in front of the speaker. You will be impressed once you hear it plays classical and jazz music. Here is the photo taken from a HiFi friend in Macau. He loves the sound but want more level so he paralleled 2 pairs. The footprint of Spectrum VI is just 12" x 12" and ~ 48" tall.

Hi etsang3 hing,
My Marantz PM-5 is still working, only:
1) Volume control sometimes cannot detect both
channels.
2) The Volume Meter doesn't work, may be
something burnt inside the PCB.
3) The Class A Button seems no function.

Thanks

Cominox兄,那是因為膽機那班友仔炒膽炒到離譜,當人家是羊,花多多錢結果聲音回報只是微乎其微,因為買回來的東西的市價按其聲音表現比率嚴重脫節,只要是膽就炒到天價,與其要花一筆錢,倒不如花在更實際的石機層面上更好,很多時都可以找到好東西,而且,優質石機其表現其實很好,價錢有OK,我都轉用石機啦,正是那班炒家自食其果的時候了

Dear etsang3. Thanks for the info on TRP. I did come across a TRP factory visit report in the Chinese Wireless World back in the 60s. I vague remember the factory was in Kowloon Bay and I saw the photo of its production line. Was my memory right?

There was also one very impressive pair of speaker I saw in Moutries in Central, perhaps in 1969. It was large must be 25 in wide and 40 in tall, with many mid drivers and tweeters (cannot remember and one large woofer. It was playing with a McIntosh amp when I saw it. It was one of my most hifi moments in my memory. Do you know anything about that Radio Peoples speaker?

BTW, Audax is one of the best sounding speakers I like.

hkmk 兄,多謝讚賞。

ttvfwong hing, ..factory at Kowloon Bay... yes. you may be right. Most of the time I will be at showroom and just sometimes I will go to ShamPoKong to visit the warehouse and also the TV (B&O) and HiFi service center there. I still remember another Master, Mr, Fung there. TRP also did professional acoustic system (PA amplifier and Recording Studio equipment). That's why I can get 2 16" Wharfedale woofer back home for DIY. They are spare of Lee Theater of that time. Those days were fun.
While I was working there, I could only see the small and the tall TRP Sepctrum loudspeakers.

Hi etsang3兄,

實在是一位難得的HIFi醫生, 本人從不懂電子為何物, 但真的喜歡一些年事已高的器材(補回少年時買不下來的遺憾), 但他們往往都有問題, 若本人像樓主一樣有這樣的維修奶O, 幸福不少

etsang3 兄

我有d個人心得唔知有無用, 如果舊膠開始硬化無咁有彈性, 又或者個裂口比較受力的話, 可以切一塊細少的樹膠片, 以混合膠補上去作為強化, 呢個方法甚至試過用係大眼乾衣機隻門個彈力扣都頂得順架.
