    A pair of AR-3 fell into my lap this week

    You can get Lacquer Thinner at Home Depot.

    I don't think it was irrelevant and I do think Daytons are horrible as a series cap as per my experience. But thank you for clearing up who said what.

    Roy, where did I say the Clarity caps had a warm sound? I made a comment that they didn't exhibit glare and brightness that the Daytons did and thus were a better cap for that situation. Yes, I could hear the difference in an AB test and so could someone who didn't know what was different in the xover. I also mentioned the speakers no longer got under my skin after just 20 minutes of listening.

    If you look at the surround roll at the 10 o'clock position it looks spliced but I'm unable to see the splice in either the inner or outer lip. The picture gets fuzzy when I enlarge it too much.

    I used Mundorf ECap70 on my 10Pi but used the Vishay 1837 0.01uF bypass on the two series caps. They sound wonderful. As good as my 91s with the Clarity CSA + AudioCap Theta 0.01uF FF caps on the series caps. But I run the 10Pi on a 60wpc tube amp and the 91s on a 500wpc Class AB Studio Reference amp.

    That's a parallel cap and the frequencies are shunted to ground. You really shouldn't 'hear' it. I too use Daytons in that position. Let us know about the Jantzen Superior cap.

    I have no issue with anyone using Dayton caps or whatever cap they want. They simply did not work out in my 91's as a series cap for me. I was never able to listen to them for much more than 20 minutes with the Daytons when listener fatigue would really get under my skin. An A/B test with one having the Clarity caps and my son and I could hear a difference. The Dayton exhibited glare and brightness/white noise. I'm quite happy with the Clarity. I used NPE (Mundorf ECap and Bennic) in my 10Pi and they sound every bit as good as the 91's but I did use Vishay 1837 0.01uF film bypass caps on the two series caps.

    I've used those yellow 10uF film caps. Pretty nice in what I used them in. Wish they still had more.

    The cheap dollar LCR meters typically do not measure at 1kHz which is what you want to test most NPE caps at. Film caps don't seem to be affected too much by the very low test signals in the cheapo meters.

    Simply my experience. Nothing more, nothing less. I always remember Ken Kantor's remarks:

    The Parts Express 150uF comes in an NPE. The Parts Express caps are made by M.D.L. I have (2) Erse 150uF NPE if you want them. They measure: 149.7 and 150.6 at 1kHz You may not like the Dayton film caps. They are OK for shunt caps but I find them horrible for a series cap. Clarity CSA are wonderful in AR speakers IMO.
