Hallicrafters S 38e Schematic -

: The schematic covers 4 continuous bands spanning from 540 kHz (AM broadcast) all the way up to 32 MHz.

: The circuit features a multi-component ceramic network often called a "couplate" or "printed component". Many restorers suggest bypassing or building a discrete replacement for this part on the schematic, as the internal original capacitors leak over time and can cause alignment issues or poor audio. Hallicrafters S 38E Schematic

: Unlike earlier S-38 models that used older octal tubes, the "E" version transitioned to seven-pin miniature tubes. The classic lineup includes: 12BE6 : Converter / Mixer 12BA6 : IF Amplifier 12AV6 : Detector / AVC / Audio Amplifier 50C5 : Audio Output 35W4 : Power Rectifier : The schematic covers 4 continuous bands spanning

will provide the most complete commercial service documentation. 📻 S-38E Technical Highlights : Unlike earlier S-38 models that used older

You can locate high-quality scans of the original factory circuit diagrams and alignment steps across a few classic web repositories:

Keep these notes in mind when reading the schematic or sourcing replacement parts:

⚠️ : The S-38E utilizes a transformerless AC/DC design (similar to the famous "All-American Five" radios). Depending on which way the original, non-polarized plug is inserted into a wall outlet, the metal chassis can become connected directly to the "hot" side of the 120V electrical main.
