This was a hard one for it is build for performance and not for ease of servicing. The separate, closed up servo section is hard to get to. Couple of capacitors were suspect, so I re-capped this unit using Low ESR and high temp/long life Nichicon and Nippon Chemi-Con made capacitors.
Some of the features:
- Excellent SPDIF coaxial output which is in fact better than most transports
- 4 digital outputs: TOSLINK, Glass Optical, SPDIF and AES/EBU
- 4 digital inputs: like above
- 4 x Burr-Brown PCM-1702 ladder DAC chips with laser trimmed resistors
- Burr-Brown op-amps and buffers
- Fully balanced with 4 separate channels for hot and cold for each channel
- 2 extra amps with inputs taken from balanced amps for the single ended outputs on RCAs
- extra stable clock with 4 separate crystal oscillators !! (never seen before)
- Sony KSS-151A magnetically driven mechanism
- VRDS CD clamp bridge made from die-cast steel
- shielded servo cables which are also grounded
- Faraday cage encased servo board
- remotely controlled preamp ready to drive power amp directly
- heavy case milled from single piece of steel.
- laser only 20% used up, so with 80% remaining it should be good till end of century

This unit needed really a basic service of belt replacement and limit switches cleaning to get it going mechanically and had a minor fault of one audio buffer failing (BF634). Some alignment, nothing major but time consuming nonetheless to do it properly.
