Below are the links for the hespedim from both the levaya here and in Eretz Yisrael.
Levaya of Chaim Yissachar Feigenbaum in America
Divrei Hesped for Chaim Yissachar Feigenbaum from Eretz Yisrael
1) you may have to download them to listen (for some reason it is not
streaming on its own)
2) they both start a few minutes into the audio so just fast forward a bit
(They will be posted under R' Moshe Tzvi Weinberg's page on YU Torah as well)
We miss you Chaim...
