Here is a mistake - a marketing mistake.
The TC-K60 was adorned with two high-end features : LCD meters and AMS. The former was until then reserved for high-end units, and the latter was, in '79, still part of the battle for ultimate convenience which mainly took place through the ELCASET format.
LCD peak meters were here controlled by the CX-765 IC.
But the K60 wasn't a high-end unit : it had only one motor, only one capstan, only two heads and still bore mechanical transport keys...
In fact, it could be seen as a step back from the earlier TC-K8B - even the LCD meter was smaller ! The AMS feature was to make up for all this.
However, the K60 wasn't a bad deck at all : it is a rugged deck with a BSL motor, programming abilities up to 9 selections, F&F heads and, mainly, Sony's excellent LCD meters.
It didn't sell much, though : too expensive for most and not offering the "semi-pro experience" three-head decks were at the time meant to offer.
