This is a rare and collectible set from our personal collection.  

These were not at all easy to find and put together, and is the result of searching over many years to find the right pieces.  Pieces that were not rusty from being stored a damp basement, pieces not missing knobs, and pieces that were not beyond repair. 

These are both super unique in their design, especially the preamp.

Full dual mono design featuring discrete signal paths for the left and right channels. If you were to use a bandsaw and cut this unit in two, you would end up with two mono preamps (not completely true but close enough to make a point).

The signal flows from right to left and all connectors are on the sides of the unit. The volume and input selector shafts extend through both channels making it possible to have a single knob for operation.

It also has a super convenient phono cartridge loading selector knob on the front, whereas most preamps would have this buried inside.

The amplifier is a perfect match and unique in its own way as it features a selector switch for Class A or Class B operation. I don’t think I’ve ever seen that before, and it's brilliant.

It is heavy and built like a tank. Parts quality is amazing from the brushed metal face plate to the internal component selection.

If you like tape decks there is a matching model from this same series which we have been unable to find in working/fixable condition.  The TCK-88 / TCK-88B. Should you actually have one for sale we would love to hear from you.

Condition is superb, with no real noticeable scratches or dents, just a tiny nick near one fo the rack ears.

Operation is spot on and has been fully tested in our lab and listening room over a lengthy period of time.

These are wonderful pieces of audio history from Sony, truly rare and special, and would make a great part of your collection.
