[Milsurplus] Vibrators

[aGEnuine Ham]

This is sort of on topic...............

I recently reassembled a GE Progress Line mobile radio from 1954 for a
vintage police car restoration.  It uses the dual interruptor vibrator,
Mallory 1701 or equivalent.  Based on my previous experiences with
vibrators, I hardly expected to find an operational one, but the first
three I pulled out of the vibrator stash all vibrated on initial
application of power.  I did not try to decipher the date codes on them,
but they have been in dead storage for at least 20 years, so not all
vibrators die in storage from sulfur contamination of the contacts.  I
regret I did not record the manufacturers, but all 3 were different
manufacturers.  I shipped all of them to the restorer along with the
radio in case he gets serious about making the receiver work.
