The jug says RCA service & since most RCA service
customers had X warranties I doubt they used RCA unless
they had to.
The EIA number is not RCA but I dont remember who it is.
Its familiar, probably one of the many small rebuilders.
The date code looks like 0991. The last time I put a
new jug in a roundy was mid 70's a Zenith combo. Strange....
73 Zeno
