(ET) relays

[Neil Dennis <wombatt gmail com>]

Good morning, Hump,  tested those two relays on DC, both pull in at 
about 20 volts drawing about 100 ma. 

One is a GE, marked as 115 volts, 60 cy.  part no A410-65857-00  6 pole 
double throw, other is Guardian Electric  marked G-56605  725 ohms 
double pole double throw.

I agree, without a diode and probably cap to filter, a relay make a nice 
buzzer, we used to make step up power supplies switching transformers 
and stuff.

Mystery continues.
