Thanks to all for the suggestions. Here's a summary since several
asked me to share.
For the caps:
47u's at 450v
100u's at 450v
General concensus is the original 10u was too low impedance.
For the resistors:
20k's at 10 watts
47k's at 5 watts
100k's at 2 watts
200k's at 5 watts
Several suggested the 47's and 100's, and metal-films rather than carbons.
Not sure what I'll use just yet until I dig through a few more junk piles.
Thanks again and Happy Holidays.
