You, the remote broadcasts or the fact that you're on a
non commercial radio station?

You probably won't find a plug and play or drop in replacement
filter. But you need to be more specific... do you want to
do standard voice remotes as in typical short traffic reports?
... or do you want to do extended voice broadcasts with possible
other source material added in. The former is easily done
with standard wideband fm radios, the other is more often done
with wide bandwidths.

It's probably not something he's been required to do in past.
And he may not be honestly interested in doing one now.

As wacky as your post reads, I'd also probably have doubts
about helping you with a hi-fi audio repeater. "Hi-Fi" and
"repeater" don't normally get used in the same sentence. You
haven't been clear about what type of material (content) to
be sent through this magic box.

www.qrz.com Would an Amateur License be required to build
a repeater? I wouldn't think so, although it would be handy.

have?
God I hope not... and no I don't think so.

In the 144-148 MHz band? Tube type equipment you think will
have better audio than some of the newer stuff? Some of the
group readers are falling back over in their chairs reading
what you're trying to do... and how you're going about it.
> what suppliers carry older motorola radio parts?
No suppliers really, but there are at least 12 full size
battleship loads of surplus NOS Motorola Parts, which have
not yet made it to the recycler or landfill. You're going
to have to do some flea markets (Like the Dayton Hamvention)
and a lot of searching around.
When you come back down to the real world, ask companies
like Comm-Spec if they have anything close in their crystal
filter retrofit kits. Otherwise it's not that hard to make
filters.
Life goes on...
