All Zeniths with true RAT were cable ready EXCEPT the B&W's cited
by RTVNUT. IIRC the first RAT set was L-line 2nd gen (9-160) System 3.
1st gen K-line System 3 ( power transformer ) had presets.
They MAY have dropped in rats at end of K-line like there are a
few J-line System 3 25" top of line that did not say System 3. The early releases were often limited distribution area wise eg only in L.A. etc.
