I was under the impression that Zenith used RCA and Mullard semis. The Zenith cross reference lists only one Amperex tranny, not used in the 1000 or 3000. Do you have any transistors so marked? All of mine clearly have RCA's EIA code of 274 on them, with one TO-7 transistor having RCA and 274 marked about 120 degrees opposite each other.
