I’m about to recap my dm 7 mk1’s. I’ve got the original crossover drawing and it doesn’t match the crossovers themselves in as much as they’ve put 1x4.7uF where there should be 2 x 1.5uF’s in parallel for the tweeter. They’ve also completely omitted a 1.0uF in the woofer side. Basically the entire crossover is full of 4.7uF’s. :scratch:By the looks of it they’re all original too. I’ve found some polypropylene film capacitors on the bay (cylindrical shape unfortunately and 630v not 100v) . Questions are:
1. should I just replicate what’s there or fit to the original drawing?
2. Any better places to get matching caps from?

I can't see the circuit diagram clearly unfortunately but if they sound good as they are I wouldn't change them. I don't think those caps (polyester) age much either unlike the round (electrolytic) ones.

Why do you think the crossovers need re-capping?
