I think you will do better by asking this question in the Minnesota
newsgroup, mn.general

I will post there, but in the meanwhile I sure could use your help.

I put the capacitor figures in the message, so future folks looking for
this rare capacitor will have some help. So while it's asking for a
local answer, this post will archive this capacitor's location for
future reference. Non-MPLS folks can order one up.

Also, after some research, I learned you can replace this capacitor
with a 6800uf 50v type. Using one with slightly higher voltage rating
is perfectly OK
