Does anyone sell an EMP-resistant tube radio these days?

    So did the early models of the F-4 Phantoms. I think they switched over to SS in the C model.

    I'm "Up For It" Jacquet. I still have "your" Swan-1200x :) - I even have a Realistic DX-302 I'll include with our "deal" ;) (I know that you had one once & this one is in excellent shape)

    Just let me know the dates. I'm only 60 miles away from the Cracker Barrel on Pine Forest Rd.

    On the subject of EMP,... I found this article to be an interesting read:

    P.S., I'm glad to see that the 500c is still in use ... :)

    I suppose you expect to spark replies to that story?

    IMO, the main problem with SS rigs is custom numbered semiconductors and chips. And those "generic" replacement semiconductors & chips never work quite right especially in RF circuits.

    Reminds me of a airborne radar countermeasures receiver dating back to WW II. All identifying information was removed from the tubes and all components under the chassis were painted brown so they couldn't be identified if the rig was captured.

    Yeah, as if that would fool the Wilhelmstrasse gang!

    Reminds me of the sealed epoxy tone modules in old Standel amplifiers.

    Memory jogged: the manufacturer was Hitachi and the time frame was the early 1970s.
