To be honest I am becoming less enamored with Duelund. With Jupiter who needs the crazy expense and I am hearing of leaky CAST caps regularly from folks. Duelund is very good about replacing leaky caps for free and that is a good thing.
I am also confused as to what a CAST cap is! The .22uf one in my work room, cut in half, has no paper in it and has layer after layer of thin plastic or Mylar stuff. No joke guys.
I sense the lower voltage crossover CAST caps, the ones that are wide and flatter, are the most special ones.
I just purchased some Jupiter copper foil caps for speakers. The new 100 volt caps. I will report back to all once they are in.
Thus far the high voltage Jupiter caps have bested the high voltage CAST caps in the electronics I have used. We will see how good the 100 volt crossover caps are soon. The 3.3 uf caps cost $200 each and are not cheap, but they are still priced well under CAST. They go on sale for 20% off at Parts C and Sonic Craft reducing the cost to $160 each.
