This was used on Zenith 14 & 16" hybrids. Also Pannys & IIRC a
few other JA sets.
Later it was on GE porta colors & the 16" dog, a rare set that was probably
the biggest POS built til the Chi-Com sets.
Sylvania used it in the E08 with in line jugs.
For manual just look for Panny CT### early sams. IIRC the 19" Pannys used
a normal 3 clover.
