[Milsurplus] Vibrator Replacement Challenge

[B. Smith]

        I propose that those that have experimented with various 
vibrator circuits  actually construct and "test" their circuit in an 
actual  piece of military equipment .  The AN/GRR-5 filament vibrator  
would be an ideal subject. Then after testing publish this information 
either on the web or in a publication such as "Electric Radio".

      This vibrator replacement would either be housed in the original 
can or be small enough to mount in the space that the original vibrator 
housing  occupied and must be operating at the correct frequency. The 
circuit would utilize the original vibrator socket and contain its own 
heat sink.  And hopefully this replacement would be as quiet across the 
spectrum as the original vibrator.  :-)

      Its one thing to theorize and play with vibrator replacement 
circuits on the bench but in the end actual testing in a power supply 
mounted in a piece of equipment is necessary. But most important - 
document and  please share the information with others.

      I realize that there are several vendors that advertise 
replacement vibrators for automobile radios etc., but this challenge is 
for older vintage military equipment.
