Help Understanding ACC

[old_tv_nut]

By the way, why I asked if tube or solid state:
The Subcarrier Regen Module B+ pin says 12.36V (obviously way over-precise reading, suspect the nominal is 12V), and the Chroma Module B+ says 22.6V, high for an analog IC.

When I was developing analog ICs for TV video and chroma circuits Zenith had settled on 12V B+ for all analog ICs.

Do these modules have ICs or only discrete transistors?

The video processor, subcarrier and chroma modules have ICs.
