Letter Re: Zenith “Trans-Oceanic” EMP-Proof Shortwave Radios

I just realized something that some of the SurvivalBlog readers might find interesting: All the older Zenith Trans-Oceanic radios have replaceable (“socketed’) transistors.
The Zenith Trans-Oceanic radios model 1000 and 3000 all have Sockets. I recently replaced a PNP transistor in a 1962 Sony with a new 2N3906 and the radio worked!
So, if someone buys one of these older multi-band shortwave radios with the transistor sockets, then they should buy a bunch of cross-referenced transistors and place them
in a small metal can to protect them from EMP.  See: http://www.transoceanic.nostalgiaair.org/3000.htm
Open the PDF file and you’ll see the transistor sockets. They even tell you how to fix/align/tune this radio. I’m sure the designers wanted this radio to last forever.
President Johnson had a 3000 in the White House that he used to listen to regularly.

It’s to bad the GE Superadio does not have sockets. But the older Zenith Trans-Oceanics with transistor sockets are almost as sensitive as the Superadios and the Zenith’s are made to last! – Fred The Valmet-meister
