If you own or are restoring a Hammarlund SP-600, one resource you need to know about is Perry Sandeen’s An Anthology of Technical References for the Hammarlund SP-600 and its Variants. This is a comprehensive compilation covering the SP-600 receiver family and its many variants, assembled over a long period with contributions from numerous collectors and restorers in the amateur radio community.
Perry made this anthology freely available through the Boat Anchor Manual Archive (BAMA, and it remains one of the most thorough single-source references for SP-600 work. With approximately 39 different SP-600 variations produced between 1951 and 1972, having a consolidated technical reference like this is invaluable for anyone doing restoration or alignment work on these receivers.
The anthology is available as a single complete PDF or split into two parts for easier downloading:
