    Very nice capacitor grouping!

    Question: what is “sweet”? I can understand the clarity and definition is superior with the teflon capacitor, but I’m not quite “getting” what is superior with the better paper and oils. More 3d imaging? Better harmonic saturation?

    The one capacitor that probably should have been included was the Jupiter condenser capacitor (..despite tempo electrics marginal rating). I wouldn’t be surprised if it was very similar to the paper tube Jensen copper while being about half the cost.

    Here are some additional links:

    Again, thank you very much for the testing!

    Hi ScottG,
    It’s a little bit difficult to define “sweet” by word (perhaps due to my limited vocab in English). I think we can also use “warm” or “mellow” (but not “dull”), which you can “taste” the lips, tongue, even singer’s breathe when singing. I think this refers to better harmonic saturation also. Like comparing a 300B tube vocal vs solid state vocal. Perhaps with this you can understand what do I mean by “sweet”.

    We can’t make a general assumption about all Paper-In-oil Caps, since not all of them have similar sound. Let’s say Audio Note vs Jensen Paper-In-Oil. Even they both same Paper-In-Oil, but Jensen has better high frequency tones, while perhaps Audio Note has even “sweeter” vocal. More different if you try Jensen Paper Tube or Duelund.

    I have tried Jupiter once… but this caps had gone away long ago (I sold it to my friend). Perhaps just not my cup of tea. If I could recall my memory correctly, the tones of this Jupiter is between Audio Note Copper and Jensen “classic” Copper. To Jensen Paper Tube? I can’t confirm, but I don’t think so.

    And as my caveat has been written, the result my subject to the listener preference. YMMV.

    Thanks for the links.

    Thank you for the reply Jimmy!

    I can understand that 300B vs. solid state (..well, good solid state).

    You could well be correct about the Jupiter capacitor. Note though that their materials/mechanical formulation has changed (..though for all I know it could be worse).

    Anyway, again a big thank you!

    (BTW, loved the use of the CD cases for the switch face-plate.)

    Dear ScottG,
    Thanks for your comments.

    I have moved your comments to here:

    Just to make the discussion easier to be followed.

    Thank you.



  7. Face Says:

    In reference to your recent cap comparisons. You should give the Claritycap ESA a try as a coupling cap. It doesn’t compare to Duelund of course, but it has a nice warm tone to it and is very affordable. They’re also very compact in size. For a little more transparency and a little more high end tilt, the Claritycap MR is also a great coupling cap. Both are also just as impressive in speaker crossovers.



  8. Jimmy Auw Says:

    Hi Face,
    Thanks for your information. Too bad when I bought all caps from PCX, they didnt carry ClarityCap. Here in my country (Indonesia), hardly to find a good caps. So I need to buy overseas. From your description, I think the ESA could be similar to Jensen. But if I could recall my brain correctly, the MR also quite expensive.

    Thanks.

    Hi Face,
    In the future, please post it here:

    Not in this about page. Just to simplify the discussion.

    Thanks.

    dear jimmy, i hope you can help me with my problem. i own a konzert ks-8w subwoofer(this is the only sub i can afford)but unfortunately the toroidal transformer was burnt, i forgot the unit to turn off after listening a number of songs. it just stays on for almost one day. since in our place there was no support from konzert, so i opt to buy an ei type transformer since there is also no available toroidal transformer here. the rating of ei is 18v-0-18v, 3Amp. the rating of thr toroidal trans is 17.5v-0-17.5v, i don’t know the ampere rating but it has 220VA printed. now my problem comes in here, all relevant connection to the transformer was already done by soldering. but when i turn on the switch, the fuse would suddenly blow. i would replaced it again and still it would blow. what is supposed the problem? i hope you can find time answering me. i was really thankful i come across on your website. than you and god bless. eric

    I happen to have a black plate RCA 12b4a NOS tube and 3 NOS 6bq5/EL84 tubes. Are you interested in them to purchase?



  12. stenor Says:

    Hello Jimmy I’ve been reading your journal/articles/blog..? with great interest for some time. And now I’m looking to take advantage of your experience (mwahaha) *evil laugh*. Well, that is if you’ll allow it. I’m making psu for some nxV300 modules (aussieamplifiers) and aiming for 60-100k uf per channel, toroid +-500va (dual mono). I need advice on caps to use, they shouldn’t be ultra expensive, but they could be “a little expensive” if that give much improvement.
    So, you have any good advice? (oh, and they should be about 100v 8-15k uf range)



  13. Jimmy Auw Says:

    You can try Jensen 4-pole.

    Thanks.

  17. LPark Says:

    Jimmy, can I get your comments on Mr. X’s RS241 amplifier? I’ve been looking to go for one, and I was interested in getting it made by tube lovers indonesia… pls email me at lindenpark at gmail dot com, thanks!!!



  18. Jimmy Auw Says:

    Hi,
    If you are on the way of 300B or 2A3, then this RS241 should be on the end of your journey.

    Thanks.
