[Premium-Rx] Looking for Rare Part for Rare Receiver

[Joe Watson]

I have acquired a PR-700A spook radio (for surveillance and monitoring) made by Micro-Tel Corporation in Baltimore.  It is very interesting radio and is operational on the bands up to 30 MHz.  
It has a defective wide-band amplifier module which is used on all ranges above 30 MHz (it goes up to 2 GHz).

This module is a small cube of aluminum about 1 " on a side with mini coax in and out. plus a power terminal for 15 VDC.  The amplifier inside is an AVANTEK UTO-2021 thin-film circuit.
I have found a supplier or twp for a new UTO-2021 circuit but they want over $200 for it.  Does anyone out there have something similar that might work?  I know it is along shot, but I needed to inquire. This is a wide-band amplifier that the antenna signal passes through and would need to be usable over the 30 to 2000 MHz range.

If anyone has something that might work or has any advice for me (other than "buy the $200 unit") I would be interested.

Thanks.
