I've put my answers below David's questions. Apols for the delay in
replying; I was travelling for business the last couple of days and only
got home in the early hours of this morning.

Some more information would be useful.
-- Which ambisonic mic were you using?
Brahma, going to a Tascam DR-680 recorder
Other mics were a pair of Line Audio CM3 sub-cardoid pencil mics to
boost the outer sides of the choir (if necessary) and a Recording Tools
MRP-01 ribbon mic for the soloists
-- Does the buzz really only appear when the organ and brass are playing?
Actually really only when the organ is playing; the brass is usually
with the organ, but not always. The buzz is present when the organ is
playing loudly.
-- Is the buzz heard both in loud AND soft passages?
No, only when the organ is quite loud
