At least for now, I am going to only scan and post schematics & parts lists like this one featuring the Atwater Kent Model 305Z 5-Tube 32 V. D.C. Superhet radio in graphical format, rather than run OCR on them to separate the textual content. There are still many people who restore and service these vintage radios, and often it can be difficult or impossible to find schematics and/or tuning information. I will keep a running list of all data sheets to facilitate a search.

Radio Service Data Sheet

(Has 3 wave bands; dynamic speaker; dual-lighted dial.)

The voltages for this receiver are shown on the schematic diagram near the portions of the circuit to which they apply. When aligning the set, the volume control should be turned on full and the tone control set at high pitch. For trimming the R.F. end of the set, it is best to connect a 250 mmf. condenser in series with the antenna lead of the set. When the I.F. is aligned, one of the manufacturer's coupling units should be connected, the unit being placed on the control-grid cap of the I.F. or first-detector tube as needed, and the lead from the circuit connected to the coupling unit. The dial pointer should be at 538 kc. when the rotor of the tuning condenser is fully meshed. The short-wave range is aligned at 15 mc. and the broadcast range at 1,500 and 560 kc. There is no trimmer for the police band. Align the I.F. transformers at 264 kc.
