[Premium-Rx] Need ST88777 Front End Module for Racal 3711 RX

[Ron Ott]

This is not the same as the Front End Module for a Racal 3701, I tried a swap and the processor doesn't recognize the different module.  The original module has a couple faults that I am unable to repair because it uses surface mount components.  The 3711 goes to 40MHz and the 3701 does not.
 
My Racal 3711 Front End Module reads "Dwg. No. ST88777" on the top, I'd love to find a minty one in working condition. 
 
Thanks, Ron W6XY
