Before Restoration

We evaluated this deck with a non-operating transport and concerns involving the capstan motor circuitry. The playback and recording electronics, mechanical controls, and tape path were also identified for service.

During Restoration

Transport Inspection: We inspected the transport mechanism, motor operation, and tape-drive components.

Capstan Motor Circuit: We inspected the motor-control circuit and associated electrical components.

Reel Motors & Brakes: We checked the reel-drive system and transport braking functions.

Record & Playback Electronics: We examined the preamplifier circuitry and signal paths.

Electronic Components: We checked aging components in the relevant transport and audio circuits.

Tape Heads & Guides: We cleaned and inspected the heads, capstan, and tape-contact surfaces.

Pinch Roller & Tape Path: We inspected the pressure roller, guides, and tape travel.

Switches & Controls: We cleaned and serviced accessible switches and mechanical controls.

Reverse-Playback System: We inspected the reverse-playback mechanism and related sensing components.

General Mechanical Service: We cleaned accessible transport assemblies and checked their mechanical operation.

After Restoration / Final Testing

We carried out functional inspection of the transport and audio controls following servicing.

We reviewed the deck’s playback and recording signal paths as part of the final service process.
