As for how-why that wasn't done in the first place... I think, back then they could only manufacture ceramics of up to some-100 nF. > Alternatively wiring 2 identical electrolytic cpacitors anode<>anode (or Cathode<>Cathode - > it doesn't matter which) creates a bipolar capacitor with 1/2 the > capacitance of one of the capacitors.

As such construct operates, I can't really imagine how either of the caps _never_ receives some small reverse polarity charge. AFAIK alu electrolytics do tolerate that, but tantalums generally do not. Tantalums also aren't generally used in analog filters so that I could have relied upon some confirmed-to-work solution. I didn't want to risk. Best regards, Levente Message was sent through the cbm-hackers mailing listReceived on 2015-07-22 09:00:08
