[AMRadio] Looking for very old ER article, not available from ER.

[Mike Durff]

In ER#2, there is an interview by Bill KD0HG (SK) with Kenneth Richardson on the state of tubes.

I am looking for a copy of this article. It is not available from ER, nor do I find it on the Internet. Apparently, it was published pre-internet.
Thanks, Durff, K4TQF
