Picked up a Collins 70E-22 PTO. This is used in ARC/38. There
is a highly official notice on the side of the unit that states that it
has been MODIFIED FOR SSB, note: refer to TO covering
SSB mod.

Can anyone clue me in on what this modification might entail?

Also, this PTO has many more wires than usual connecting to it.
Would welcome pointer to a schematic or other information on
how it would be connected up.
