In 1968 Tandberg updated the ageing Series 12 so as to incorporate the new crossfield bias system. The new model had the designation 1200X.
Available in either half-track
or quarter-track configurations the 1200X resembled its predecessor very closely. Apart from the crossfield head the only other outwardly obvious change was a double VU meter with indirect illumination
replacing the Model 12’s EAM 86 magic eyes.
Three speeds were provided, 7½ , 3¾ ,
and 1 ips and there was a four-digit revolution
counter (also indirectly illuminated).
