I might have that part in my IC Stash, I can take a look for you if you want, I had picked up several years back at the local SA Thrift Store a couple of baskets of TV Repair Parts that came from a local appliance repair shop that closed up shop and I have a lot of RCA, Zenith and Philips IC Chips.

UPDATE: I just checked through my IC Chip Stash and unfortunately I did not have the exact part number you need for your set, I had many chips that came close to your part number you needed (many of them from the CTC17x series of color TV Chassis) but not the exact part number so I unfortunately don't have the part you need like I thought I did.
