The Hallicrafters service manual provides detailed instructions for setting up, operating, and troubleshooting the Model SX-62/62U receiver, which is a high fidelity superheterodyne receiver capable of receiving AM and FM broadcasts across a wide frequency range. It includes guidance on power source connections, speaker and antenna setups, and features such as an automatic noise limiter and a built-in calibrating oscillator for accurate tuning.
Manual Overview
The Hallicrafters Model SX-62/62U service manual provides detailed instructions for troubleshooting, calibration, and operation of this high fidelity superheterodyne receiver. The manual emphasizes the importance of accurate dial calibration, facilitated by a built-in 500 kHz crystal-controlled calibrating oscillator and adjustable dial pointer. This feature ensures precise tuning across the frequency range of 540 kHz to 109 MHz, covering AM and FM broadcasts. Troubleshooting guidance includes checking power sources, with the receiver operable from both AC and DC sources. AC operation requires a 105-125 volt, 50/60 cycle outlet, while DC operation involves a 6-volt battery and a 270-volt DC supply. The manual advises careful adjustment of the power transformer selector switch for universal models to match local voltage requirements. Speaker connections are provided for 500 and 5000 ohm outputs, and antenna connections accommodate both single wire and doublet configurations. The manual also highlights the receiver’s adjustable selectivity for various broadcast types and an automatic noise limiter to reduce background noise.
Quick Issues Covered
- Diagnose power-up failures with AC and DC source checks.
- Calibrate dial using built-in 500 kHz crystal oscillator.
- Use schematics for circuit tracing and troubleshooting.
Overview

Installation / Setup
The installation/setup highlights for the Model SX-62/62U receiver include:
1. Unpacking: Carefully check all shipping instruction tags before removing them.
2. Location: The receiver is equipped with rubber feet for table top or shelf mounting. Avoid placing it in excessively warm locations like near radiators or hot air registers.
3. Power Source: The receiver can be operated from an AC source (105 to 125 volt, 50/60 cycle) or a DC source. For AC operation, ensure the jumper plug is in its BATTERY POWER receptacle. For DC operation, a 6-volt DC source and a 270-volt DC supply are needed, with specific voltage and current requirements.
4. Speaker Connection: Three screw-type terminals on the rear chassis apron are provided for speaker connection, with output impedances of 500 and 5000 ohms.
5. Antenna: A three-terminal strip is available for antenna connections, accommodating either a single wire antenna lead-in or antenna transmission line. For a single wire antenna, connect a jumper between terminals “A2” and “GND” and attach the antenna to terminal “A1”. For a doublet antenna, it is recommended for high-frequency bands.
Ensure to read the installation section of the manual before connecting to a power source.
Operation
The Model SX-62/62U receiver is a high fidelity superheterodyne receiver designed to cover broadcasting services between 540 kilocycles (KC) and 109 megacycles (MC). It can receive FM and AM broadcasts within this range. The receiver features a built-in 500 ke crystal-controlled calibrating oscillator for accurate dial calibration, with marker signals every 500 ke on the dial scale. This allows for precise logging of shortwave stations and active communication channels directly on the dial. The receiver’s selectivity is adjustable to accommodate both broad and sharp responses required for different types of reception. It includes a high fidelity tone compensated audio system with four distinct tone ranges for entertainment and communication purposes. An automatic noise limiter reduces background noise with minimal audio distortion. The receiver can be disabled temporarily with a RECEIVE-STANDBY switch without waiting for tube heaters to warm up. It operates from a 105-125 volt 60 cycle AC source, with an option for external battery operation in areas without AC current. A universal model supports operation from 25 to 100 cycle AC sources at voltages from 105-250 volts.
