[R-390] Microphonic tubes

[jcoward5452 at aol.com]

HI all,
 That was a great video!

My microphonic radio is a very nice example of the Zenith "Bomber" 7G605 TransOceanic portable. When operating it will, on ocassion, let out a very etherial moan which I find quite endearing as it tells me that this radio bemoans its lost past and the history that was told through its tubes and speaker  to those souls who once gathered 'round to listin in.

Now if my R-390A did that it would have to report behind the wood shed after chores were done!
