help settle a squabble

[ONETINSOLDIER 2]

Im a member on an audio forums and a debate has started on wether the military had used any tube-type electronic equipment in jets, submarines, etc, and wether they would be subseptable to vibration with concerns to loss in audio quality. Im aware of the fact that "hi-fidelity" really isnt a concern when chasing down the bad guy in the mig, but I guess it might be a concern regarding radar and ECM.

I guess reading the thread might help explain too, heres a link if interested, http://www.audiokarma.org/forums/showthread.php?t=266190 (focus on post #6)

Thank you for any input,

Valve electronics was all they had back in the 40's when they put airborne radars into Nightfighters... Also all the early radios etc would have also been valve types Transisters didn't really come into it until around the late 60's and early 70's...

 

Tried the link but it didn't work...

 

Hope it helps

Radars, radios, ECM units (etc) all had vacuum tubes through the early 1950s. Transistors started replacing them in the 1950s, and had pretty much taken over by the mid-1960s. Radars were still using Klystron tubes and magnatrons well into the mid 1970s. Phosper radar displays (as opposed to CRTs) were still common place into the mid-1970s, early 1980s.

I quite a few RADAR's currently in use still use Magnetrons...
