Use metal films everywhere, except where there is a risk of a large 
surge current (for example, the resistors between sections of the 
electrolytic filter capacitors on the B+ supplies, where there could be 
a significant turn-on surge).  Even there, if you use MFs with twice the 
rated power of the original CCs, you will be fine.

Best regards,
