Need Part for Zenith Chromacolor-2

[robert1]

I am in dire need of a 212-149 HV Trippler for a Zenith Chromacolor 2 that is the set my wife mainly watches. the trippler (which was original) finally failed after 39 years of use. the chassis is a 25JC49 & uses a oddball trippler, the ECG 526 or 528 will not work because of this trippler has a extra connection marked as "refference".

does anyone here know of a resource as where i can find one? prefferably a N.O.S.
thanks.
please pm me if you may have info on one.
