Common Issues and Solutions
Transport Mechanism Problems
The ATR-60 features an advanced transport system that can develop specific issues:
- Tension arm problems: Worn bearings or misalignment cause irregular tape tension
- Capstan motor issues: Hall-effect sensor failures or motor driver problems affect speed stability
- Brake system wear: Worn brake pads cause inconsistent stopping
- Guide alignment: Tape guides can become misaligned, causing edge wear
Electronic Issues
Common electrical problems include:
- Capacitor failure: Electrolytic capacitors dry out, causing noise and performance issues
- Relay contact oxidation: Causes intermittent operation or channel dropouts
- Power supply regulation: Failed regulators cause voltage fluctuations
- Op-amp deterioration: Aging ICs cause noise and distortion

Mechanical Maintenance Procedure
- Disconnect power and remove covers
- Carefully clean the transport mechanism with isopropyl alcohol
- Inspect and replace worn brake pads if necessary
- Remove old hardened lubricant from all moving parts
- Apply fresh lubricant to appropriate areas:
- Capstan bearing: Special capstan oil
- Guide rods: Light instrument grease
- Levers and pivots: Light machine oil
- Check and adjust tape tension using proper tension gauge
- Clean all switches and potentiometers with contact cleaner
- Clean tension sensors with isopropyl alcohol
- Inspect and align tape guides
Note: The ATR-60 uses precision heads that should be cleaned regularly with isopropyl alcohol and a cotton swab.
Avoid abrasive cleaners. Demagnetize heads regularly for optimal performance.
Calibration Procedure
After capacitor replacement, these calibrations are essential:
- Set playback level and EQ using MRL calibration tape
- Adjust record level and bias for each tape type
- Check and adjust tape tension across all modes
- Verify tape speed accuracy at all speed settings (7.5, 15, 30 ips)
- Adjust head azimuth for proper high-frequency response
- Calibrate reproduce and record electronics for all channels
- Set proper brake tension for smooth operation
- Adjust tension arm positions for proper tape handling
Additional Tips
- Use high-quality, low-ESR capacitors for longer life
- Document all adjustments before making changes
- Check all resistors near replaced components; they may have drifted in value
- Clean the record/playback switches thoroughly as they often cause noise
- Allow the unit to warm up for at least 30 minutes before making final adjustments
- Consider replacing relay contacts if they show signs of pitting or oxidation
- Use deoxit on all edge connectors and reseat all boards
