Volume control for Philco 65 - BrendaAnnD - 04-02-2015

Where is this in the schematic/circuit? I'm looking at the schematic trying to find it so I can try to help someone out with a problem (volume control is running hot?), but I don't even see a volume control in the schematic at all.

Has to be the item that is labelled #1 (listed as 10,000 ohms on the first page) doesn't it??  Just drawn funny, as though the wiper is at the high ohm end of the pot?

Part (25), 1,750 ohms. It controls the screen grid voltage of the two 224 RF amps.

Thanks. I did find it after I posted this.. it's just in a very odd spot on the schematic so I didn't find it right away.
