GM List,

I had a bad senior moment on my capacitor posting.  Here is the corrected thought plus a past reflector post.

Use polypropylene media Orange Drop capacitors for circuits operating at 455kc and below. If you want to be really fancy, bypass those with a .001 ceramic disk. I get my Orange Drops from Antique Radio: http://wwwtubesandmore.com

Use 1KV Ceramic discs for frequencies above 455KC

I believe that the correct use is disk caps for RF and orange drops for audio.

I agree while it is best to use foil types, I'm not sure that metalized foil caps that are of the orange drop style from a high quality Mfr. wouldn't be fine.   Especially if one upped the voltage rating.

It does come down to a price issue for some.

Sorry for the confusion.

Regards,

Perrier
