There was a factory forced air ass'y for MICOR repeaters? (other than for
the 1/4 KW?) I know a few 100W 2-Meter and UHF 75-watt MICOR repeaters that
need something like that, although muffin fans above the heat sink probably
work fine, too.

I agree about collecting Micor parts ... goes for GE-cor (Ok, Mastr
II) too. The manufacturers haven't been supporting those radios in
a very long time, you you don't sandbag for the day when you might
need some spare parts, who will?
I nearby friend just unloaded 8 more Micor cabinets with various
radios in them last week.
Part of that includes:
C42RCB - 72-76 MHz Micor Station
C71RTB - 42-50 MHz Micor Station (a two freq transmitter & 2 one
freq receivers.)
C53MHY - 150.8 - 162 MHz - continuous duty repeater. (Came with
the factory blower assembly.)
Multi other stuff too.
Ok, who is looking for what? I have enuf here to be able to part
as the need ariszes.
