Thanks, yes I read your article long time ago and do remember you having discovered in 38-690 the tweeters are wired in counterphase, and I will correct that.
As to the value of the cap, I put in 1.5uF (the article says 2.2uF is needed) at this point and I will listen to it first; I do have a suitable 4.7uF cap if they will lack the response.
About the electrolytic: I would support that theory but the Aerovox put it on the label which is weird, at least. It almost looks like "our microfarads are better than other people's microfarads and so our replacement ratio is 1:5 as our farads simply perform better".
PS. Are you saying that 1uF was an electrolytic cap? It cannot be, as it is supplied with AC input, that would kill it. Was it really?

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
