[R-1051] Navy and Air Force R-1051B 100cps modules are incompatible

[L D Ritta]

Hello All
When did they start making the r-1051b, I had a r-1451a receiver by Sylvania
built in 1966 which used nixies
But were driven using flat pack ic's and I think have fets. I don't have the
r-1451a anymore, which had most of the
Circuits diagrams.

At least it didn't blow anything up, like when you drop a 100cps module into
a plain mainframe.
