ideas on this model?

Late '70's-early '80's. Uses the 9-160 system 3 chassis.

inline all SS then?

Yep, inline CRT and all solid state. Those 9-160 chassis sets made a good picture; but, they could be a pain to work on and the CRT's didn't hold up as well as the older delta gun tubes.

I got one of those sitting right here. The phosphor is pealing off the inside of the crt starting at the bottom right corner. You can see right through to the mask inside.

decent sets.the very beginning of zeniths decline.looked good when new,but crts went south early.brightness issues with resistors on crt socket board and generally not a high quality set
