My CTC-16XL Project.

While I wait for the parts ( coming tomorrow ) , there is something I've been wondering, on the schematic, (sams ) it refers to “spark gap” in a few places, like C155, but it is a normal cap, and not a spark gap capacitor, with slits in the top like I have seen before, but, they do have the leads of this cap routed in heavy stock cardboard, in what could be a spark gap configuration, is this what they mean perhaps?

Yup!

If you ever do a late 60's-mid 70's Zenith they use two pieces of magnet wire bound together with cloth shrink wrap. Anything (or rather any two things) conductive CAN be a spark gap if you want it to be, and there were plenty of things engineers tried to make them out of.
