RCA 7027A Matched Pair Vintage Audio Vacuum Tubes:
$81.00
Excellent Condition Matched Pair RCA 7027A Vacuum Tubes. As I have little knowledge of tube testing and operation, I sent the tubes out for testing. The tubes were tested on an Amplitrex AT1000. Per the testing company \"The 7027A\'s are fine and are as new\" The results of the testing are in the last picture. The date code on the matched tubes is ABN. I am also listing the other 7027A single tube (#9) that was tested.

Per information provided by a person knowledgeable on tubes: They were most likely made by GE around 1978 as RCA ceased tube producton by the end of 1976.
