dcuhl, the 250v does say something about the ac. We have 120v ac which is RMS voltage. There is a calculation to find out what DC voltage rating will be adequate. Caps, much larger than .1 can or do improve bass performance and spacial stuff a bit. One friend of mine when I gave him a large cap for across the line said it sounded tube like. 250V is safe for 120ac as long as it is X type safety cap. If you have a 250v or higher film cap around I doubt if it will fail in the time you take to hear it although technically you should always use the X type. Digikey has loads of them. T EDIT The factor for dc voltage for peak dc voltage, not peak to peak is 1.414. 1.414x120=170 so 240v is fine. I'm almost 100% certain peak to peak is not used. I have used 240v caps for years and years.
