Blacet Dual Filter bare PCB cap- and IC question

Post by e-grad » Tue Oct 07, 2008 8:40 am

Hi list, this is my first posting and I'm coming right with two questions. Hope to contribute later myself!

I've got two Blacet Dual Filter bare PCBs and two questions regarding them:

1) The BOM asks for mylar caps (C1; C2; C5; C6) which are hard to come by in my part of the world. Thus I'd like to substitute them for polystyrene. Is that fine or a little over the top?

2) I need in total four MAX365 ICs, alas, I could track down only two. Any source?

BTW Blacet hast still some Dual Filter bare PCBs. After having heard some samples (I think by Kwote), I think it a very nice Filter. However, if you buy one or more take the knob kit as well if you want to pcb mount the pots since two of them have 6 pins each which should not be easily to find elsewhere.

Polystyrene would be fine. They are actually better than mylar but you probably wouldn't notice the difference in a manual filter. I'd suggest going for polyester if you can find them for cheaper than the polystyrene.
