chris ma
Anybody wants to get rid of their decent input caps in the range of 1uf to 3 uf. Please let me know I may be interested to buy it off you.

Regards,
Chris
Peter Daniel
If you want to experiment, I can send you some on condition that thay will get back to me after the experiment, and you can also buy the ones you like.;)
li_gangyi
What if I dun keep the promise...which I might wanna break after seeing those caps...
chris ma
Peter,

That's an offer nobody can refuse.
Thanks, we can arrange that and I promise not to use the blow torch butcher style on them.:) and take good care of them until I paid you then is another story, muuhaaha

Hi li_gangyi,
That's a very good idea, but unfortunately Peter already knew where I live. I like where I am living now too much for the sake of a few caps;) a few ladies maybe haha

Chris:smash:
li_gangyi
Wow...and you get to try them out...and pay for the best~!!! Gimmi the rest~!!! I mean the ladies...chuckles...

Have you try any of them personally? In what league you would rank those caps? Is the seller trust worthy? More info please..

Chris
li_gangyi

You ever tried those guys?? How is the cap..and their service?
chris ma
I have a reply from the seller who called himself (blow-up) and there was no detail on how to make payment arrangements except he was kind enough to quote the shipping/postage cost out from Taiwan.

Is he doing this as a business or he just has some surplus stocks to sell..? Or is Coffin is the same guy as Blow-up?

It is a little bit uncertain whether he is a serious seller or not!

Regards,
Chris
li_gangyi
Yeah...his website also gives me that kinda impression..not to say he's not a serious seller..I'll bet some people might have giotten their stuff from him...but wouldn't using E-bay or atleast a better webpage be better?? Instead of just using E-mail to buy and sell stuff...
coffin
Hi
The website is indeed too simple. I build it for my friend although I'm not good at it.

Originally I test it on my own homepage to see if there's any problem, and came out to be unstable because GEOCITIEs will be unreachable sometimes.

After that I sent the page to my friend and close the original one. He put it on the other place and asked me to post it here. end of story.

If there's any misunderstanding, I'll apologize here.

Coffin

PS. I had used his caps on my Pearl phono stage. Superb.
li_gangyi
then I'm sure it'll be worth a try~!!!
Peter Daniel
Chris,

I'm sending you those caps to exeriment;)
li_gangyi

Peter Daniel
After much hesitation I decided to also include those caps, as they seem to me the best sounding of the whole bunch

Shipping to Singapore is a killer of a deal. The amp modules cost to ship USD 45. Are you up for that?;)
li_gangyi
USD45 huh??
I could probably get tt kinda money in a few WEEKS time...can you wait?? and I was referring to caps here...but NVM amp modules first...what is the expensive aprt?? Air frieght?? Weight?? you could...try to reduce it's weight...by removing the unnessary stuff...I only need the heatsink and baord...ok if you wanna include caps...I dun mind...
li_gangyi
Ok...just took a look at it again...seems like there's no way to reduce it's weight...just wanna know...what is the 45 bux for?? Air Friehgt?? I can go by Surface mail...even though it's kinda slow...but cost savin...hai~~~ Singapore is just too far away...with USD45 bux..I could've just add in a few more hundred...and gone to ur place...
Peter Daniel
That's surface. I can't wait on that as I already have two other offers from US.
li_gangyi
hmmm...then I guess I'll have to pass...just one of my bad days...guess living in Singapore has it's disadvantages...

Thanks Peter this is great, appreciate that..
:)

I have to set up some kind of docs in a table format to record my review of those caps..

Those look suspiciously like motor start caps...often PIO or MKV...

I do recall Dice45 claiming the Siemens/Epcos MKV caps were the best he'd ever experienced.

There are still some vendors in Germany selling those, as anyone tried them?

They're not all that expensive...

What gives?

Cheers,;)
Peter Daniel
Those are Simens MKV and I agree with Dice. Although the ones pictured are not the best grade, they outperform all the other caps I tried in sense of naturalness and neutrality. I like them especially in tweeter networks.

Always same ole' story with Siemens....they make the best and than abandon it or sell it....******.

Still, there's hope...there are still a lot of Epcos caps around and they're considerably cheaper than most other boutique caps.

It wouldn't surprise me one bit if these would turn out to be great in tube PSs and as coupling caps...

I'd better shut up now or I'll be left with nothing to buy...shhhhttt...

Cheers,;)
li_gangyi
so those are really motor run caps?? hmmm..I might try one of those...maybe flood my whole amp with them....

Experiments are done, please look out for them before the weekend and let me know everything is fine.

Thank you again
Chris
li_gangyi
So in your opinion which caps are the best?? I might try getting them if they are good...

The most suitable caps for my amps is the one that I did not send back to Peter.
And the keeper is S+M

If Peter do not mind then I will try to summarised the rankings of those caps for my particular system conditions IME or IMO of course.:)

Chris
li_gangyi
hey~!!! That's the motor run cap?? it's so whooping big...and I think it's self healing...gotta get some of those soon...
PAM
I'm doing some test with motor caps from INCO.
The are very big PP caps with 500 V AC (1200 V DC)
And the are costing only 10,75 euro for a 10 uF.

In the documentation from INCO I can reed that they don't use aluminium as foil but a silver/zinc alloy. The electical performance improved much better.

I know a German loudspeaker with motor caps (Terizan)

The only problem is to get those caps. I had succes in a washing machine shop.

Has anybody did some testing in loudspeaker X-overs ?

I would be very interested myself to hear your observations.

I tested all those caps in tweeter crossover, and Siemens was my definite choice, as the treble sounded least colored and most natural when it was used.
chris ma
The follow caps are listed in the order that I will pick to use for the latest pairs of my updated JLH using MJ21194, CLC power supply with 22-0-22 400VA, Iq set at 3A. Small copper clips with Belden hook up wires are soldered between RCA center pin to amp board used to prevent unnecessary soldering when changing caps. Volume control setting remained constant at the pre-amp. Mute and source toggle switches were used when changing caps.
Amps stayed power on to maintain same heat sink operation temperature at 46 degree Celsius during testing. A pre-selected number of tracks of several CDs were used repeatedly.

1/ S+M MKV, most natural sound, good balanced gain, dynamic overall
2/ Surplus Aerovux 2uf oil can(my own) bypass with small cap of 100nf (my own), similar to S+M but gain is higher, just lost by a hair on finer detail clarity.

From here on the list are like second class caps
3/ MIT MultiCap 2uf, sound ok and balanced in gain but a bit veiled/congested
4/ Jensen paper in oil bypass with MIT MultiCap 0.47uf, sound good and smooth at first, very strong coloration give you the false sense of reality, still sound good to the ears though. But it is not my cup of tea.
5/ PB470 ST MKP 4.7uf(my own), natural sound, less gain, dynamic not as good
6/ INFINCAP Wonder 5uf, sound a lot louder in bass but boomy
7/ Hovland Musicap 1.8uf, sound like small Hi-Fi system, way too much coloration, and cloudy.

From here on the list are like third class caps, nothing special, sound a boring
/ PPE-MKP-FC 2.2uf
/ WIMA MKS 10 - 2.2uf
/ MIT MultiCap 4.0uf

Ran out of time and not tested, kept going back to 1 and 2 to listen to compare.
/ Nichicon 44 – 5.6uf
/ AEON FINE CAP 4.7uf
/ UNKNOWN B 32231 4.7uf

May I suggest bypass the oil cap with a 0.1uf or 0.56uf Russian Teflon cap (search ebay using "teflon cap*") I think you will like the result.
li_gangyi
yeah a guy named KWTubes on Ebay has got a lot of Military grade stuff..a link here.

Peter Daniel
I was bypassing those caps with 0.022u silver foil caps and didn't like the results. I found that most coupling caps work better without bypasses.
agent.5
I noted a typo on my prior post. It should say 0.1uf or 0.056uf teflon cap. I guess the edit function does not work after long idle time.
