I have owned several dozen pairs of Tung-Sol 6AS7G tubes and I've never seen one that could possibly have been a relabeled RCA. And many pre-date Tung-Sol's acquisition of Chatham Electronics. Doesn't mean it never happened on occasion though. I have a Tung-Sol .6SN7GT which is definitely Sylvania made, which is funny because Tung-Sol made LOTS of 6SN7 tubes.I can't say for sure about Raytheon and Sylvania 6AS7's . Might be RCA made. Might not.
