[ARC5] BC-669 Vet Project: PE-110 Power Supply

[David Stinson]

Thanks, J.
Yes; it has a vibro-pack so the receiver can be used with just the 
mobile 12-volt battery supply.  One started the little PE-108 generator 
to get the Transmitter high-voltage.
I think one of the members probably got it right;  the 12 VDC relay 
physically looks just like the original 115VAC relay.  Some field tech 
went to change the relay and installed the wrong one. Must have been a 
common mistake because I've seen it before.  Once the 12V relay was in, 
when the radio was keyed, the "new" relay buzzed louder than hair 
clippers.  That's when the radio went on the "look at me one of these 
days" shelf and thence, out to surplus.  I'd bet coffee and donuts 
that's what happened.  The 12 VDC and 115 VAC relays look identical 
except for the rating printed on the side of the coil.
