[Drake] Looking for a Drake MSR-2 receiver manual

[Meir Ben-Dror WF2U]

Folks,

I came into a pair of MSR-2 receivers in "unknown" condition. I found one is sort of working with some issues. The second one doesn't turn on, I suspect the power supply. For further troubleshooting it's essential I find the complete manual whether an original, a hard copy or a good PDF version. All I managed to find online is a DSR-2 version manual PDF, which is helpful since most modules are identical to those of the MSR-2, but the latter has additional preselector and input protection  circuits.
I'd appreciate any info regarding acquiring the manual, and any experience with MSR-2 problems to share.
