The Heathkit Troubleshooting Tips manual provides guidance on common issues and solutions for various audio equipment, including AA-Series amplifiers and AD-Series audio systems, addressing problems such as power switch failures, hum and noise, and slow changer action. It also covers troubleshooting for AJ-Series tuners and AR-Series receivers, offering specific checks and adjustments for issues like motorboating, muting action, and FM sensitivity.
Manual Overview
The Heathkit Troubleshooting Tips manual provides detailed guidance for diagnosing and resolving issues across various Heathkit audio and electronic equipment. For AA-Series amplifiers, common issues include power switch failures in the AA-22 and normal hum in the AA-29. AD-Series audio equipment, particularly those with BSR-500 changers, may experience slow speed and changer action, which can be addressed by adjusting or replacing the idler wheel and cleaning components with a non-lubricating solvent. The AD-110 model requires attention to capacitor C2 for excessive meter deflection issues. AJ-Series tuners, such as the AJ-15, may have motorboating issues linked to a shorted Q503, while the AJ-29’s muting issues can be traced to a leaky ZD-211. AR-Series receivers, including the AR-1500, have specific calibration requirements for FM-IF DC voltage and RF levels, with adjustments needed for optimal performance. The manual emphasizes the importance of precise calibration, component replacement, and board-level adjustments to maintain equipment functionality and performance.
Quick Issues Covered
- AA-22 power switch frequently breaks down, causing power-up issues.
- AD-110 excessive meter deflection in record mode; check C2 orientation.
- AJ-15 motorboating with headphones; inspect Q503 for shorts.

Troubleshooting & Error Codes
The troubleshooting guidance from the manual includes various issues and solutions for different Heathkit products. For the AA-Series Amplifiers, the AA-22 model has a common issue with the SPST pushbutton power switch breaking down. The AA-29 model may exhibit hum and noise, which is considered normal.
In the AD-Series Audio Equipment, slow speed and changer action in systems with BSR-500 changers can be addressed by checking and cleaning the idler wheel and associated components. Tone-arm issues in AD-17 and AD-27 models may require checking the pivot screw or adjusting the anti-skate mechanism. The AD-110 model has specific guidance for excessive meter deflection and bias adjustment levels.
For AJ-Series Tuners, the AJ-15 may experience motorboating with headphones, which can be resolved by checking Q503. The AJ-29 model may have no muting action due to a leaky ZD-211. The AJ-33 model’s DPDT slide switches may need cleaning or tightening.
AR-Series Receivers have various issues such as motorboating at turn-off in the AR-13, which can be fixed by checking capacitors C17-C18. The AR-15 may have oscillation issues at the speaker output, and the AR-29 may have a mute function issue similar to the AJ-29. The AR-1500 has guidance for poor FM sensitivity and specific voltage and RF level measurements.
C-Series Automotive products like the CI-1079 and CO-1015 have issues related to specific IC brands and sweep linearity, respectively. The CO-2500 tachometer may have jitter or intermittent operation, which can be addressed by checking socket pins.
E-Series Educational Products like the ET-3400 may have display issues due to grounding problems. G-Series Digital Clocks have various issues such as count jumps, brightness discrepancies, and erratic operation, each with specific solutions.
GD-Series Radio Control products may experience interference due to metal-to-metal contact or jittery servos, which can be resolved by adjusting motor wiring.
