Leslie schematics page, most of the hammond b3 service manual scans are from Xeroxes of old manuals and are ment as help for home-tinkerers like myself, so the scan quality may vary.
The document cross references Hammond part numbers found on the schematics to generic part designations Series 10 tone cabinet PR-40/QR-40 (early units) P-40/Q-40 (including instruction sheet, zipped) HR-40/H-40 (various versions, zipped) JR-20 (early units) JR-20 (code 'B JR-20 (code 'C' with bass compensation switch) PR-20.
