Why was the 6AS7 dropped as a TV damper?

What sets used the 6AS7G as a damper? I would like to see if it was just connected as a diode or if the grid control actually served some purpose.

Sure, a diode or double diode would be cheaper to fabricate than a double triode. Bean counters usually win.

I don't remember any other set using it for a damper but the first post-war GE, model 801???
IIRC, the RCA 648*** projection set used one as a damper.
I just scrapped a mid-60's Techtronics that had one. I is a "G" type branded RCA, with a mid-60's code date.
