I have a pair of S75 speakers that I quite enjoy and wanted to take the time to throw new caps in them. Run into a couple questions:
1. The original caps from W. Germany are still in. Service manual (see below) states a 50uF cap @ C1 & C5. In both locations there is a 47uF. I have both values of identical npe in stock but is there a best practice?
2. The original resistors I’ve read to be in need of replacement. All are 3W resistors. Is there a baseline W rule of thumb for resistors in crossover? I have a bunch of 10W resistors that will work and fit, albeit tightly. Maybe 10W is overkill.
3. Lastly to reach some of the needed cap values I’m adding two smaller caps. Is it best to keep cap values similar when doing this? Ie on a different job I needed a 28uF and opted for 22+6.8 over 12+15 to keep it closer to original spec with what I had on hand but perhaps I should have gone with the latter.
