Electrolytics rated to handle the line voltage will do the job. I like to build a little 'buffer' zone into the circuit if I can. I've seen spikes on our Michigan grid hit way above suggested line voltage. I like to build a little insurance in if I can. I have not seen issues with increasing working voltage to double live voltage on sets I've replaced them on. Not saying it can't happen, just hasn't with me. Since you're replacing 20MFD caps with 22MFD caps the drop should still keep the value near 20MFD +/- 20 percent. That's my story, and I'm sticking with it! Please correct me if my reasoning is in error... that's how I learn! Take care and BE HEALTHY! Gary
