Yes.
EFL came out in H-line on 17 & 19" just the high end sets.
Chassis was a lot like CC2 re-arranged.
Got rid of the 9-89 r-g-b out & put it on the CRT SKT.
9-147 vert replaced with 9-120 & separate beefy outputs.
150-190 IF got -01 added & had a SAW filter.
New tripler for the 3 focus grids.
Other boards got updates & -## Some things got moved around.
Service wise the same as CC2 for the most part, EASY !

Zenith EFL tubers and ALL others like them...do NOT have the "bulletproof" design of their chromacolor delta tubes. Those Tri-potential tubes were dying OVER 25 YEARS ago !!
