Chances are, if your R-390A could play from its past, it would be classified.

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!Jay KE6PPF-----Original Message-----From: Barry <n4buq at knology.net>To: r-390 at mailman.qth.netSent: Wed, Jan 27, 2010 7:53 pmSubject: [R-390] Microphonic tubesSince we have discussed the effects of microphonic tubes before, I thought ou guys would enjoy this one:http://broduke2000.livejournal.com/87950.htmlI hope no one has a tube that bad in their radio...Barry - N4BUQ ______________________________________________________________-390 mailing listome: http://mailman.qth.net/mailman/listinfo/r-390elp: http://mailman.qth.net/mmfaq.htmost: mailto:R-390 at mailman.qth.netThis list hosted by: http://www.qsl.netlease help support this email list: http://www.qsl.net/donate.html______________________________________________________________R-390 mailing listHome: http://mailman.qth.net/mailman/listinfo/r-390Help: http://mailman.qth.net/mmfaq.htmPost: mailto:R-390 at mailman.qth.netThis list hosted by: http://www.qsl.netPlease help support this email list: http://www.qsl.net/donate.html
