I'm just about to order all the new parts for the upgrades to the SDA-1C's. I realize that many of these questions have been posted before, but, to be honest, sometimes the search function fails me. Can the experts please educate me a little....
1. There are capacitors on the wiring diagram labeled "electrolytic, Mylar, and Silver dipped mica." Can I just replace ALL of these with film-type caps of the same uf (or pf, as applicable) value?
2. So far, the caps I've found online (Solens, Sonicaps, etc.) have different voltage values than the original ones on the crossover board, and occasionally slightly different capacitance values. Is there any harm in using caps of different voltages, and within a very close tolerance of the original capacitance? For example, one of the original caps is a 4.4 uf Mylar 100V. Can I replace it with a Sonicap 4.3uf 200V without harm, or a Solen 4.3uf 400V PB cap?
3. The original resistors are all rated at 5W. Is there any advantage or disadvantage to replacing them with 12W resistors (from Mills)?
4. Can I opt NOT to use the 750pf bypass cap in the tweeter circuit? If so, what might be the predicted results?
I thank you all for your help; the forum has been tremendous in getting some of my questions answered.
