[time-nuts] Service manual or schematic for 1050A ?

[Tom Knox]

I was wondering if anyone has a service manual or schematic for any generation of the FTS, Datum, Symmetricom, Microsemi 1050A oscillator? I have several of these and although quite old still have state of the art performance, unfortunately I have several with PLL issues. Schematics and information on the physical configuration of the coaxial jumpers on different revisions would be great. 
Thanks;
