Audioengr, there are no polypropylene RELcaps in the JC-1, but there is 108v and 95vdc so be careful poking around it there! Rost, you nailed the break-in as you think it is done at thirty days and is a little boring and then they open up as you mentioned.....Oh, audioengr, the caps are polystyrene with tin plates and that isn't why they take so long to break in BTW......Oh, I selected the parts for the unit....
