Professionally refurbished and recalibrated

To ensure excellent sound quality and long-lasting reliability, this Onkyo TA-2550 has undergone a comprehensive technical overhaul. The maintenance was carried out with the utmost care and focused on all critical mechanical and electronic components.

Maintenance work carried out (excerpt):

Drive & mechanics:
- All drive belts were replaced.
- The pressure roller was thoroughly cleaned or (if necessary) replaced.
- The capstan bearing was cleaned and refreshed.
- The entire drive mechanism was re-oiled and re-greased with special, age-resistant lubricants.
- All switches in the drive have been cleaned.

Motor overhaul:
- Each of the three motors was removed and underwent extensive maintenance.
- This includes servicing the motor bearings and checking internal components to ensure stable and quiet operation.

Electronics & controls:
- All relevant switches and potentiometers (controls) on the front of the device were cleaned to guarantee trouble-free operation without scratching noises.
- The electronics were visually inspected and any known weak points were treated preventively.
- If necessary, the device display was cleaned from the inside to optimize readability.

Final adjustment & quality control

After the overhaul, the deck was precisely recalibrated according to the manufacturer's specifications:

Adjustment of the tape transport, tape speed, and playback/recording levels.
Exact azimuth adjustment (head tracking) using a 10 kHz / 12.5 kHz reference cassette.
Testing of the recording characteristics (as a 3-head device) with different types of tape and measurement signals 300 Hz - 10 kHz.
Measurement and confirmation of excellent wow and flutter values (WRMS).
A final endurance test followed by renewed cleaning of the entire tape path ensures full functionality.
