Board-level guidance includes inspecting solder joints and component placement to ensure correct assembly. The manual specifies the tube complement necessary for operation, including the 5Y3 rectifier and various amplifier tubes, and highlights the importance of using the correct power supply of 105-125 V AC. The receiver’s dimensions are provided for reference during assembly and installation.

Quick Issues Covered

• Diagnose power-up failures with tube complement checks.
• Adjust tuning range from 550 ke to 1620 ke.
• Calibrate high impedance input for optimal phono performance.

Overview

The Heathkit Broadcast Band Receiver, Model BR-2, is a radio with a tuning range of 550 ke to 1620 ke. It features a built-in high sensitivity rod type antenna and a 5 1/2″ PM 4 ohm voice coil speaker. The tuner operates with high impedance to any amplifier input with a resistance of 100,000 ohms or more, and includes a 110 V outlet for an amplifier or phono player. The phonograph stage has a 1 megohm high impedance for optimal performance with crystal or ceramic phono pickups. The tube complement consists of a 5Y3 rectifier, a 12A6 beam power amplifier, a 12AV6 detector, A.V.C. and audio amplifier, a 12BA6 I.F. amplifier, and a 12BE6 pentagrid converter. It requires 105-125 V, 50-60 cycles AC, and 40 watts of power. The dimensions are 11 1/2″ wide, 5 3/4″ high, and 6 3/4″ deep.
