[R-390] Replacement caps for HP200CD

[Scott, Barry (Clyde B)]

The HP200CD I have has two "Black Cat" caps I'm going to replace.  They are 0.5ufd @ 400VDC.  I know the standard today is 0.47ufd, but would I be better off sticking to the original value by using two 1ufd in series?  If I do, is it acceptable to use 200VDC caps?  Is there any adverse effect from doing this?

I know that caps in parallel add to the total capacitance, but each cap in this case will tend to act independently at different frequencies.  I don't think this is the case with series caps, but I'm not sure.

Thanks,
