[Boatanchors] Collins R388 Break In Switch & Circuit

[Mark Johnson]

Happy New Year Team,

I just acquired an R388 that has been through a very tough life, but like
all Collins gear, it's still working. 

I want to get it back to full form, but I can't find any info, or a  the
circuit diagram for the break in switch circuit. Lots of sources for an R388
schematic, but none of them show the break in switch circuit. I found a tech
bulletin that describes the Break In circuit, but no actual schematic. 

It just annoys me to see a radio with wires cut even if the circuit in
question is not necessary. 

Thanks!
