Info
Operation, Alignment and Service Manual for Hallicrafters S-27 receiver.
Provided by Tom Dover, WD4FFN.
NRL Report R-1840 23 Jan 1942.pdf
The graphs of selectivity etc which are in color, are particularly interesting. It was also interesting that Hallicrafters did not follow many of the NRLs recommendations from this report.
Note that the S-27C was the earlier version of the S-37. The S-27 (non-C) was the predecessor of the S-36 and S-36A.
