Does anyne have Motorola MA367 Baseband Through Channel Amps?

Does anyne have Motorola MA367 Baseband Through Channel Amps?

Does anyone know where we can obtain any Motorola MA367 Through Channel Amplifier/Filter units??

These are used for MC-22 baseband relaying schemes to pass only the relaying channel required for the relaying path.

Our unit that is defective is a 152 Khz filter amplifier.

I realize that these are OLD units.  Does anyone know of a modern filter-amp that will pass only ONE baseband channel?

Or do you have any used units that you no longer need?

We may be able to go with another frequency if we have a transmitter and receiver of the same frequency as the filter/amp.

Any help as far as a source alternate, or available equipment would be appreciated.

The filters on these units pass only a 4 Khz band with a very high rejection anywhere outside of the center freq. +/- 2 Khz.

Thank you,
