Parts Express has the caps cheap. Like $6.75 for 4.7uF as used on a tweeter. Likely cheaper than a motor run. Expensive ?????????????
Follow Ups:
I said 47 uf. You are looking at the wrong cap.
$29.50 for 47uF. That is not expensive for 47uf in a quality cap. If great audio is not important to you, then use a $10 motor run capacitor.
They are not mutually exclusive.
I have cde in my10yse ht running 18 hours a day for 8 years.Great voice.I just picked some dc link caps 900 volt 50uf for less the 20$ I think these could be the future. I am hoping there will be more of these showing up for sale. These are isckra brand and are very compact and test about .23 esr. I got some 750 75uf's also. .23 too.
Something weird some of my favorite oils tested much higher. Could this account for the tone? Could a higher esr help with stability in signal path?
I tested k72p Russian Teflon. the metal ones (not alloy). no measurable esr!? just no value where it should be. I bought more to try more in my stuff.
elna silmic tested lower then many oils!
Finally A pair of hovland foil caps I bought many years ago for the first tube preamp I ever built. Never payed so much $ since 400 volts 2uf. I tried them in lots of things. Liked them best on focal tweeters tested .3! higher then I expectedRussian red tin can cap tested low same as the dc link if my memory serves me right.
