Can anyone give me a suggestion where I can obtain some grill cloth to
replace on a Hammarlund S-200 spreaker? (This was the series of speakers
made to match the HQ 170's and 180's) Thanks in advance

I think that beautiful swirly cloth was one of a kind. If you can find
someone to make a custom reproduction, please notify this newsgroup. If not,
I'm afraid you're reduced to haunting local fabric shops, etc., for
something that looks close. I regret selling the S-200 that came with my
HQ-160 ( http://antiqueradio.org/hamm02.htm ). Oh well, there's another fish
in the sea.

There is a grille cloth supplier at http://www.grillecloth.com/ , but he
specializes in consumer radio cloths.
