[Milsurplus] Name of Navy Maintenance Manual ?

[Hubert Miller]

There is a Navy manual from postwar period which has service notes and upgrades to Navy electronics.
This is the book that has the TBX upper limit frequency expansion. Someone out there will be very
familiar with the book. Mike Roof, the fellow who authored that great article on the SCR-300, asked me
for the reference for the Navy mod of the BC-1000, the mod which added a B+ switch to the panel, to
stop the drain of the B+ battery when the radio is stored away for some time.

What i am asking: what is the name and number and year of this book ?
